Our current DDL only allows a database name to be specified in COMMENT
ON DATABASE, which Andrew Dunstan reports to make this test fail on the
buildfarm. Remove the line until we gain a DDL command that allows the
current database to be operated on without having the specify it by
name.
Backpatch to 9.5, where these tests appeared.

Hot_standby_feedback could be reset by reload and worked correctly, but if
the server was restarted rather than reloaded the xmin was not reset.
Force reset always if hot_standby_feedback is enabled at startup.

!foo means "the tsvector does not contain foo", and therefore it should
match an empty tsvector. ts_match_vq() overenthusiastically supposed
that an empty tsvector could never match any query, so it forcibly
returned FALSE, the wrong answer. Remove the premature optimization.
Our behavior on this point was inconsistent, because while seqscans and
GIST index searches both failed to match empty tsvectors, GIN index
searches would find them, since GIN scans don't rely on ts_match_vq().
That makes this certainly a bug, not a debatable definition disagreement,
so back-patch to all supported branches.
Report and diagnosis by Tom Dunstan (bug #14515); added test cases by me.

When (1) autovacuum = off and (2) there's at least one database with
an XID age greater than autovacuum_freeze_max_age and (3) all tables
in that database that need vacuuming are already being processed by a
worker and (4) the autovacuum launcher is started, a kind of infinite
loop occurs. The launcher starts a worker and immediately exits. The
worker, finding no worker to do, immediately starts the launcher,
supposedly so that the next database can be processed. But because
datfrozenxid for that database hasn't been advanced yet, the new
worker gets put right back into the same database as the old one,
where it once again starts the launcher and exits. High-speed ping
pong ensues.
There are several possible ways to break the cycle; this seems like
the safest one.

Thinko in commit a4523c5aa. It doesn't really affect anything at
present, but it would be a problem if any tests added later in this
file ought to get index-only-scan plans. Back-patch, like the previous
commit, just to avoid surprises in case we add such a test and then
back-patch it.

These macros work fine when they are used directly in an "if" test or
similar, but as soon as the return values are assigned to boolean
variables (or passed as boolean arguments to some function), they become
bugs, hopefully caught by compiler warnings. To avoid future problems,
fix the definitions so that they return actual booleans.
To further minimize the risk that somebody uses them in back-patched
fixes that only work correctly in branches starting from the current
master and not in old ones, back-patch the change to supported branches
as appropriate.

These resulted in wrong answers if the relabeled argument could be matched
to an index column, as shown in bug #14504 from Evgeniy Kozlov. We might
be able to resurrect these optimizations by adjusting the planner's
treatment of RelabelType, or by adjusting btree's rules for selecting
comparison functions, but either solution will take careful analysis
and does not sound like a fit candidate for backpatching.
I left the catalog infrastructure in place and just reduced the transform
functions to always-return-NULL. This would be necessary anyway in the
back branches, and it doesn't seem important to be more invasive in HEAD.
Bug introduced by commit b8a18ad48. Back-patch to 9.5 where that came in.

Previously multiple sessions could execute pg_start_backup() and
pg_stop_backup() to start and stop an exclusive backup at the same time.
This could trigger the assertion failure of
"FailedAssertion("!(XLogCtl->Insert.exclusiveBackup)".
This happend because, even while pg_start_backup() was starting
an exclusive backup, other session could run pg_stop_backup()
concurrently and mark the backup as not-in-progress unconditionally.
This patch introduces ExclusiveBackupState indicating the state of
an exclusive backup. This state is used to ensure that there is only
one session running pg_start_backup() or pg_stop_backup() at
the same time, to avoid the assertion failure.
Back-patch to all supported versions.

A client copy can't work inside a function because the FE/BE wire protocol
doesn't support nesting of a COPY operation within query results. (Maybe
it could, but the protocol spec doesn't suggest that clients should support
this, and libpq for one certainly doesn't.)
In most PLs, this prohibition is enforced by spi.c, but SQL functions don't
use SPI. A comparison of _SPI_execute_plan() and init_execution_state()
shows that rejecting client COPY is the only discrepancy in what they
allow, so there's no other similar bugs.
This is an astonishingly ancient oversight, so back-patch to all supported
branches.

In 9.5, the default pg_ctl stop mode was changed from "smart" to "fast".
pg_upgrade still thought the default mode was "smart" and only specified
the mode when "fast" was asked for. This results in using "fast" all
the time. It's not clear what the effect in practice is, but fix it
nonetheless to restore the previous behavior.

pg_restore will currently accept invalid values for the number of
parallel jobs to run (eg: -1), unlike pg_dump which does check that the
value provided is reasonable.
Worse, '-1' is actually a valid, independent, parameter (as an alias for
--single-transaction), leading to potentially completely unexpected
results from a command line such as:
-> pg_restore -j -1
Where a user would get neither parallel jobs nor a single-transaction.
Add in validity checking of the parallel jobs option, as we already have
in pg_dump, before we try to open up the archive. Also move the check
that we haven't been asked to run more parallel jobs than possible on
Windows to the same place, so we do all the option validity checking
before opening the archive.
Back-patch all the way, though for 9.2 we're adding the Windows-specific
check against MAXIMUM_WAIT_OBJECTS as that check wasn't back-patched
originally.

Including the program name twice is not helpful:

pg_dump: pg_dump: invalid number of parallel jobs
Correct by removing the progname from the exit_horribly() call used when
validating the number of parallel jobs.
Noticed while testing various pg_dump error cases.

If inherited tables don't have exactly the same schema, the USING clause
in an ALTER TABLE / SET DATA TYPE misbehaves when applied to the
children tables since commit 9550e8348b79. Starting with that commit,
the attribute numbers in the USING expression are fixed during parse
analysis. This can lead to bogus errors being reported during
execution, such as:
ERROR: attribute 2 has wrong type
DETAIL: Table has type smallint, but query expects integer.
Since it wouldn't do to revert to the original coding, we now apply a
transformation to map the attribute numbers to the correct ones for each
child.

... and therefore we ought not to tell XLogRegisterBuffer the opposite,
when writing XLog for a brin update that moves the index tuple to a
different page. Otherwise, xlog insertion would try to "compress the
hole" when producing a full-page image for it; but since we don't update
pd_lower/upper, the hole covers the whole page. On WAL replay, the
revmap page becomes empty and so the entire portion of the index is
useless and needs to be recomputed.
This is low-probability: a BRIN update only moves an index tuple to a
different page when the summary tuple is larger than the existing one,
which doesn't happen with fixed-width datatypes. Also, the revmap
page must be first after a checkpoint.

I posted a test case demonstrating the problem, but I'm refraining from
adding it to the test suite; if the WAL consistency tool makes it in,
that will be a better way to catch this from regressing. (We should

This fixes problems where a plan must change but fails to do so,
as seen in a bug report from Rajkumar Raghuwanshi.
For ALTER FOREIGN TABLE OPTIONS, do this through the standard method of
forcing a relcache flush on the table. For ALTER FOREIGN DATA WRAPPER
and ALTER SERVER, just flush the whole plan cache on any change in
pg_foreign_data_wrapper or pg_foreign_server. That matches the way
we handle some other low-probability cases such as opclass changes, and
it's unclear that the case arises often enough to be worth working harder.
Besides, that gives a patch that is simple enough to back-patch with
confidence.
Back-patch to 9.3. In principle we could apply the code change to 9.2 as
well, but (a) we lack postgres_fdw to test it with, (b) it's doubtful that
anyone is doing anything exciting enough with FDWs that far back to need
this desperately, and (c) the patch doesn't apply cleanly.

array_fill(..., array[0]) produced an empty array, which is probably
what users expect, but it was a one-dimensional zero-length array
which is not our standard representation of empty arrays. Also, for
no very good reason, it rejected empty input arrays; that case should
be allowed and produce an empty output array.
In passing, remove the restriction that the input array(s) have lower
bound 1. That seems rather pointless, and it would have needed extra
complexity to make the check deal with empty input arrays.
Per bug #14487 from Andrew Gierth. It's been broken all along, so
back-patch to all supported branches.

configure can only probe the existence of gcc intrinsics, not how well
they're implemented, and unfortunately the answer is sometimes "badly".
In particular we've found that multiple compilers fail to implement
char-width __sync_lock_test_and_set() correctly on PPC; and even a correct
implementation would necessarily be pretty inefficient, since that hardware
has only a word-wide primitive to work with.
Given the knowledge we've accumulated in s_lock.h, it appears that it's
best to rely on int-width TAS operations on most non-Intel architectures.
Hence, pick int not char when both are nominally available to us in
generic-gcc.h (note that that code is not used for x86[_64]).
Back-patch to fix regression test failures on FreeBSD/PPC. Ordinarily
back-patching a change like this would be verboten because of ABI breakage.
But since pg_atomic_flag is not yet used in any Postgres data structure,
there's no ABI to break. It seems safer to back-patch to avoid possible
gotchas, if someday we do back-patch something that uses pg_atomic_flag.

That was written when we still had "crypt" authentication, and it was
referring to the fact that an older client might support "crypt"
authentication but not "md5". But we haven't supported "crypt" for years.

MD5 hashes, we'll need a similar notice again. But this text as it's worded
now is just wrong.)

interval_transform() contained two separate bugs that caused it to
sometimes mistakenly decide that a cast from interval to restricted
interval is a no-op and throw it away.
First, it was wrong to rely on dt.h's field type macros to have an
ordering consistent with the field's significance; in one case they do
not. This led to mistakenly treating YEAR as less significant than MONTH,
so that a cast from INTERVAL MONTH to INTERVAL YEAR was incorrectly
discarded.
Second, fls(1<<k) produces k+1 not k, so comparing its output directly
to SECOND was wrong. This led to supposing that a cast to INTERVAL
MINUTE was really a cast to INTERVAL SECOND and so could be discarded.
To fix, get rid of the use of fls(), and make a function based on
intervaltypmodout to produce a field ID code adapted to the need here.
Per bug #14479 from Piotr Stefaniak. Back-patch to 9.2 where transform
functions were introduced, because this code was born broken.

hashname() asserted that the key string it is given is shorter than
NAMEDATALEN. That should surely always be true if the input is in fact a
regular value of type "name". However, for reasons of coding convenience,
we allow plain old C strings to be treated as "name" values in many places.
Some SQL functions accept arbitrary "text" inputs, convert them to C
strings, and pass them otherwise-untransformed to syscache lookups for name
columns, allowing an overlength input value to trigger hashname's Assert.
This would be a DOS problem, except that it only happens in assert-enabled
builds which aren't recommended for production. In a production build,
you'll just get a name lookup error, since regardless of the hash value
computed by hashname, the later equality comparison checks can't match.
Likewise, if the catalog lookup is done by seqscan or indexscan searches,
there will just be a lookup error, since the name comparison functions
don't contain any similar length checks, and will see an overlength input
as unequal to any stored entry.
After discussion we concluded that we should simply remove this Assert.
It's inessential to hashname's own functionality, and having such an
assertion in only some paths for name lookup is more of a foot-gun than
a useful check. There may or may not be a case for the affected callers
to do something other than let the name lookup fail, but we'll consider
that separately; in any case we probably don't want to change such
behavior in the back branches.

When providing tab completion for ALTER DEFAULT PRIVILEGES, we are
including the list of roles as possible options for completion after the
GRANT or REVOKE. Further, we accept FOR ROLE/IN SCHEMA at the same time
and in either order, but the tab completion was only working for one or
the other. Lastly, we weren't using the actual list of allowed kinds of
objects for default privileges for completion after the 'GRANT X ON' but
instead were completeing to what 'GRANT X ON' supports, which isn't the
ssame at all.
Address these issues by improving the forward tab-completion for ALTER
DEFAULT PRIVILEGES and then constrain and correct how the tail
completion is done when it is for ALTER DEFAULT PRIVILEGES.
Back-patch the forward/tail tab-completion to 9.6, where we made it easy
to handle such cases.
For 9.5 and earlier, correct the initial tab-completion to at least be
correct as far as it goes and then add a check for GRANT/REVOKE to only
tab-complete when the GRANT/REVOKE is the start of the command, so we
don't try to do tab-completion after we get to the GRANT/REVOKE part of
the ALTER DEFAULT PRIVILEGES command, which is better than providing
incorrect completions.
Initial patch for master and 9.6 by Gilles Darold, though I cleaned it
up and added a few comments. All bugs in the 9.5 and earlier patch are
mine.

We had an index entry for "median" attached to the percentile_cont function
entry, which was pretty useless because a person following the link would
never realize that that function was the one they were being hinted to use.
Instead, make the index entry point at the example in syntax-aggregates,
and add a <seealso> link to "percentile".
Also, since that example explicitly claims to be calculating the median,
make it use percentile_cont not percentile_disc. This makes no difference
in terms of the larger goals of that section, but so far as I can find,
nearly everyone thinks that "median" means the continuous not discrete
calculation.
Per gripe from Steven Winfield. Back-patch to 9.4 where we introduced
percentile_cont.

When we are altering a text search configuration, we are getting the

When the input value to a CoerceToDomain expression node is a read-write
expanded datum, we should pass a read-only pointer to any domain CHECK
expressions and then return the original read-write pointer as the
expression result. Previously we were blindly passing the same pointer to
all the consumers of the value, making it possible for a function in CHECK
to modify or even delete the expanded value. (Since a plpgsql function
will absorb a passed-in read-write expanded array as a local variable
value, it will in fact delete the value on exit.)
A similar hazard of passing the same read-write pointer to multiple
consumers exists in domain_check() and in ExecEvalCase, so fix those too.
The fix requires adding MakeExpandedObjectReadOnly calls at the appropriate
places, which is simple enough except that we need to get the data type's
typlen from somewhere. For the domain cases, solve this by redefining
DomainConstraintRef.tcache as okay for callers to access; there wasn't any
reason for the original convention against that, other than not wanting the
API of typcache.c to be any wider than it had to be. For CASE, there's
no good solution except to add a syscache lookup during executor start.
Per bug #14472 from Marcos Castedo. Back-patch to 9.5 where expanded
values were introduced.

You can't just cast a HashMetaPage to a Page, because the meta page
data is stored after the page header, not at offset 0. Fortunately,
this didn't break anything because it happens to find hashm_bsize
at the offset at which it expects to find pd_pagesize_version, and
the values are close enough to the same that this works out.
Still, it's a bug, so back-patch to all supported versions.

When libpq encounters a connection-level error, e.g. runs out of memory
while forming a result, there will be no error associated with PGresult,
but a message will be placed into PGconn's error buffer. postgres_fdw
takes care to use the PGconn error message when PGresult does not have
one, but dblink has been negligent in that regard. Modify dblink to mirror
what postgres_fdw has been doing.
Back-patch to all supported branches.

When dblink uses a postgres_fdw server name for its connection, it
is possible for the connection to have options that are invalid
with dblink (e.g. "updatable"). The recommended way to avoid this
problem is to use dblink_fdw servers instead. However there are use
cases for using postgres_fdw, and possibly other FDWs, for dblink
connection options, therefore protect against trying to use any
options that do not apply by using is_valid_dblink_option() when
building the connection string from the options.
Back-patch to 9.3. Although 9.2 supports FDWs for connection info,
is_valid_dblink_option() did not yet exist, and neither did
postgres_fdw, at least in the postgres source tree. Given the lack
of previous complaints, fixing that seems too invasive/not worth it.

Before commit b8cc8f947, it was possible to build contrib/uuid-ossp without
having told configure you meant to; you could just cd into that directory
and "make". That no longer works because the code depends on configure to
have done header and library probes, but the ensuing error messages are
not so easy to interpret if you're not an old C hand. We've gotten a
couple of complaints recently from people trying to do this the low-tech
way, so add an explicit #error directing the user to use --with-uuid.
(In principle we might want to do something similar in the other
optionally-built contrib modules; but I don't think any of the others have
ever worked without preconfiguration, so there are no bad habits to break
people of.)
Back-patch to 9.4 where the previous commit came in.

When dblink or postgres_fdw detects an error on the remote side of the
connection, it will try to construct a local error message as best it
can using libpq's PQresultErrorField(). When no primary message is
available, it was bailing out with an unhelpful "unknown error". Make
that message better and more style guide compliant. Per discussion
on hackers.
Backpatch to 9.2 except postgres_fdw which didn't exist before 9.3.

The U&'...' and U&"..." syntaxes silently discarded a surrogate pair
start (that is, a code between U+D800 and U+DBFF) if it occurred at
the very end of the string. This seems like an obvious oversight,
since we throw an error for every other invalid combination of surrogate
characters, including the very same situation in E'...' syntax.
This has been wrong since the pair processing was added (in 9.0),
so back-patch to all supported branches.

The ALTER TABLE documentation wasn't terribly clear when it came to
which commands could be combined together and what it meant when they
were.
In particular, SET TABLESPACE *can* be combined with other commands,
when it's operating against a single table, but not when multiple tables
are being moved with ALL IN TABLESPACE. Further, the actions are
applied together but not really in 'parallel', at least today.
Pointed out by: Amit Langote
Improved wording from Tom.
Back-patch to 9.4, where the ALL IN TABLESPACE option was added.

In pg_dump.c dumpCast() and dumpTransform(), we would happily ignore the
cast or transform if it happened to use a built-in function because we
weren't including the information about built-in functions when querying
pg_proc from getFuncs().
Modify the query in getFuncs() to also gather information about
functions which are used by user-defined casts and transforms (where
"user-defined" means "has an OID >= FirstNormalObjectId"). This also
adds to the TAP regression tests for 9.6 and master to cover these
types of objects.
Back-patch all the way for casts, back to 9.5 for transforms.

We didn't start ensuring that all built-in objects had OIDs less than
16384 until 8.1, so for 8.0 servers we still need to query the value out
of pg_database. We need this, in particular, to distinguish which casts
were built-in and which were user-defined.
For HEAD, we only worry about going back to 8.0, for the back-branches,
we also ensure that 7.0-7.4 work.

When CREATE OR REPLACE VIEW acts on an existing view, don't update the
view options until after the view query has been updated.
This is necessary in the case where CREATE OR REPLACE VIEW is used on
an existing view that is not updatable, and the new view is updatable
and specifies the WITH CHECK OPTION. In this case, attempting to apply
the new options to the view before updating its query fails, because
the options are applied using the ALTER TABLE infrastructure which
checks that WITH CHECK OPTION is only applied to an updatable view.
If new columns are being added to the view, that is also done using
the ALTER TABLE infrastructure, but it is important that that still be
done before updating the view query, because the rules system checks
that the query columns match those on the view relation. Added a
comment to explain that, in case someone is tempted to move that to
where the view options are now being set.
Back-patch to 9.4 where WITH CHECK OPTION was added.

Oversight in commit b8cc8f947. I just noticed this causes compiler
warnings on FreeBSD, and it really ought to cause warnings elsewhere too:
all references I can find say that <arpa/inet.h> is required for these.
We have a lot of code elsewhere that thinks that both <netinet/in.h>
and <arpa/inet.h> should be included for these functions, so do it that
way here too, even though <arpa/inet.h> ought to be sufficient according
to the references I consulted.
Back-patch to 9.4 where the previous commit landed.

The calculation didn't take into account the NULL terminator. That lead
to overwriting the palloc'd buffer by one byte, if the input consists

This is a trivial update (consisting in fact only in the addition of
a comment). The point is just to get back to being synced with an
official release of tzcode, rather than some ad-hoc point in their
commit history, which is where commit 1f87181e1 left it.

When there is both a serialization failure and a unique violation,
throw the former rather than the latter. When initially pushed,
this was viewed as a feature to assist application framework
developers, so that they could more accurately determine when to
retry a failed transaction, but a test case presented by Ian
Jackson has shown that this patch can prevent serialization
anomalies in some cases where a unique violation is caught within a
subtransaction, the work of that subtransaction is discarded, and
no error is thrown. That makes this a bug fix, so it is being
back-patched to all supported branches where it is not already
present (i.e., 9.2 to 9.5).
