This includes code comments and documentation. No backpatch as this is
cosmetic even if there are documentation changes which are user-facing.

Two closely related bugs are fixed. First, xmin of logical slots was
advanced too early. During xl_running_xacts processing, xmin of the
slot was set to the oldest running xid in the record, but that's wrong:
actually, snapshots which will be used for not-yet-replayed transactions
might consider older txns as running too, so we need to keep xmin back
for them. The problem wasn't noticed earlier because DDL which allows
to delete tuple (set xmax) while some another not-yet-committed
transaction looks at it is pretty rare, if not unique: e.g. all forms of
ALTER TABLE which change schema acquire ACCESS EXCLUSIVE lock
conflicting with any inserts. The included test case (test_decoding's
oldest_xmin) uses ALTER of a composite type, which doesn't have such
interlocking.
To deal with this, we must be able to quickly retrieve oldest xmin
(oldest running xid among all assigned snapshots) from ReorderBuffer. To
fix, add another list of ReorderBufferTXNs to the reorderbuffer, where
transactions are sorted by base-snapshot-LSN. This is slightly
different from the existing (sorted by first-LSN) list, because a
transaction can have an earlier LSN but a later Xmin, if its first
record does not obtain an xmin (eg. xl_xact_assignment). Note this new
list doesn't fully replace the existing txn list: we still need that one
to prevent WAL recycling.
The second issue concerns SnapBuilder snapshots and subtransactions.
SnapBuildDistributeNewCatalogSnapshot never assigned a snapshot to a
transaction that is known to be a subtxn, which is good in the common
case that the top-level transaction already has one (no point in doing
so), but a bug otherwise. To fix, arrange to transfer the snapshot from
the subtxn to its top-level txn as soon as the kinship gets known.
test_decoding's snapshot_transfer verifies this.
Also, fix a minor memory leak: refcount of toplevel's old base snapshot
was not decremented when the snapshot is transferred from child.
Liberally sprinkle code comments, and rewrite a few existing ones. This
part is my (Álvaro's) contribution to this commit, as I had to write all
those comments in order to understand the existing code and Arseny's
patch.

Bring this transform function into sync with the policy established
by commit 3a382983d.
Also, fix it to make sure that what it drills down to is indeed a
hash, and not some other kind of Perl SV. Previously, the test
cases added here provoked crashes.
Because of the crash hazard, back-patch to 9.5 where this module
was introduced.

Per buildfarm, the output from Data::Dumper for an IEEE infinity
is platform-dependent (e.g. "inf" vs "Inf"). Just skip that one
test case in the plperlu test; testing it on the plperl side is
coverage enough. Fixes issue in commit 1731e3741.

We want, say, 2 to be transformed as 2, not \\2 which is what the
original coding produced. Perl's standard seems to be to add an RV
wrapper only for hash and array SVs, so do it like that.
This was missed originally because the test cases only checked what came
out of a round trip back to SQL, and the strip-all-dereferences loop at
the top of SV_to_JsonbValue hides the extra refs from view. As a better
test, print the Perl value with Data::Dumper, like the hstore_plperlu
tests do. While we can't do that in the plperl test, only plperlu,
that should be good enough because this code is the same for both PLs.
But also add a simplistic test for extra REFs, which we can do in both.
That strip-all-dereferences behavior is now a bit dubious; it's unlike
what happens for other Perl-to-SQL conversions. However, the best
thing to do seems to be to leave it alone and make the other conversions
act similarly. That will be done separately.

PyObject returned from PySequence_GetItem() is not released. Similar code in PLyMapping_ToJsonbValue() is correct, because according to Python documentation
PyList_GetItem() and PyTuple_GetItem() return a borrowed reference while
PySequence_GetItem() returns new reference. contrib/jsonb_plpython is new
in PostgreSQL 11, no backpatch is needed.

This complies with the perlcritic policy
Subroutines::RequireFinalReturn, which is a severity 4 policy. Since we
only currently check at severity level 5, the policy is raised to that
level until we move to level 4 or lower, so that any new infringements
will be caught.
A small cosmetic piece of tidying of the pgperlcritic script is
included.

Print columns as "column C of <relation>" rather than "<relation> column
C". This seems to read noticeably better in English, as evidenced by the
regression test output changes, and the code change also makes it possible
for translators to adjust the phrase order in other languages.
Also change the output for OCLASS_DEFAULT from "default for %s" to
"default value for %s". This seems to read better and is also more
consistent with the output of, for instance, getObjectTypeDescription().

The "l" (ell) width spec means something in the corresponding scanf usage,
but not here. While modern POSIX says that applying "l" to "f" and other
floating format specs is a no-op, SUSv2 says it's undefined. Buildfarm
experience says that some old compilers emit warnings about it, and at
least one old stdio implementation (mingw's "ANSI" option) actually
produces wrong answers and/or crashes.

Previously, we passed the toplevel PlannerInfo, but we actually want
to pass the relevant subroot. One problem with passing the toplevel
PlannerInfo is that the FDW which wants to push down an UPDATE or
DELETE against a join won't find the relevant joinrel there.
As of commit 1bc0100d270e5bcc980a0629b8726a32a497e788, postgres_fdw
tries to do exactly this and can be made to fail an assertion as a
result.
It's possible that this should be regarded as a bug fix and
back-patched to earlier releases, but for lack of a test case that
fails in earlier releases, no back-patch for now.

HASH when referring to hash indexes, making it look like all the other

Someday it would be good to standardize 'B-Tree', 'B-tree', 'btree', and
random other spellings, too, but that's a larger patch ...

In 9.6, we moved a number of functions over to using the GRANT system to
control access instead of having hard-coded superuser checks.
As it turns out, adminpack was creating another function in the catalog
for one of those backend functions where the superuser check was
removed, specifically pg_rotate_logfile(), but it didn't get the memo
about having to REVOKE EXECUTE on the alternative-name function
(pg_logfile_rotate()), meaning that in any installations with adminpack
on 9.6 and higher, any user is able to run the pg_logfile_rotate()
function, which then calls pg_rotate_logfile() and rotates the logfile.
Fix by adding a new version of adminpack (1.1) which handles the REVOKE.
As this function should have only been available to the superuser, this
is a security issue, albeit a minor one.
In HEAD, move the changes implemented for adminpack up to be adminpack
2.0 instead of 1.1.

autoprewarm.c mostly considered the number of blocks it might be dealing
with as being int64. This is unnecessary, because NBuffers is declared
as int, and there's been no suggestion that we might widen it in the
foreseeable future. Moreover, using int64 is problematic because the
code expected INT64_FORMAT to work with fscanf(), something we don't
guarantee, and which indeed fails on some older buildfarm members.
On top of that, the module randomly used uint32 rather than int64 variables
to hold block counters in several places, so it would fail anyway if we
ever did have NBuffers wider than that; and it also supposed that pg_qsort
could sort an int64 number of elements, which is wrong on 32-bit machines
(though no doubt a 32-bit machine couldn't actually have that many
buffers).
Hence, change all these variables to plain int.
In passing, avoid shadowing one variable named i with another,
and avoid casting away const in apw_compare_blockinfo.

As in e348e7ae5727a6da8678036d748e5c5af7deb6c9 for jsonb/plperl, prevent
putting a NaN into a jsonb numeric field.
Tests for this had been removed in
6278a2a262b63faaf47eb2371f6bcb5b6e3ff118, but in case they are ever
resurrected: This would change the output of the test1nan() function to

Failure to use DatumGetFoo/FooGetDatum macros correctly, or at all,
causes some warnings about sign conversion. This is just cosmetic
at the moment but in principle it's a type violation, so clean up
the instances I could find.
autoprewarm.c and sharedfileset.c contained code that unportably
assumed that pid_t is the same size as int. We've variously dealt
with this by casting pid_t to int or to unsigned long for printing
purposes; I went with the latter.
Fix uninitialized-variable warning in RestoreGUCState. This is
a live bug in some sense, but of no great significance given that
nobody is very likely to care what "line number" is associated with
a GUC that hasn't got a source file recorded.

Recent gcc can warn about switch-case fall throughs that are not
explicitly labeled as intentional. This seems like a good thing,
so clean up the warnings exposed thereby by labeling all such
cases with comments that gcc will recognize.
In files that already had one or more suitable comments, I generally
matched the existing style of those. Otherwise I went with
/* FALLTHROUGH */, which is one of the spellings approved at the
more-restrictive-than-default level -Wimplicit-fallthrough=4.
(At the default level you can also spell it /* FALL ?THRU */,
and it's not picky about case. What you can't do is include
additional text in the same comment, so some existing comments
containing versions of this aren't good enough.)
Testing with gcc 8.0.1 (Fedora 28's current version), I found that
I also had to put explicit "break"s after elog(ERROR) or ereport(ERROR);
apparently, for this purpose gcc doesn't recognize that those don't
return. That seems like possibly a gcc bug, but it's fine because
in most places we did that anyway; so this amounts to a visit from the
style police.

Without these fixes, changes to the inserted tuple made by remote
triggers are ignored when building local RETURNING tuples.
In the core code, call ExecInitRoutingInfo at a later point from
within ExecInitPartitionInfo so that the FDW callback gets invoked
after the returning list has been built. But move CheckValidResultRel
out of ExecInitRoutingInfo so that it can happen at an earlier stage.
In postgres_fdw, refactor assorted deparsing functions to work with
the RTE rather than the PlannerInfo, which saves us having to
construct a fake PlannerInfo in cases where we don't have a real one.
Then, we can pass down a constructed RTE that yields the correct
deparse result when no real one exists. Unfortunately, this
necessitates a hack that understands how the core code manages RT
indexes for update tuple routing, which is ugly, but we don't have a
better idea right now.
Original report, analysis, and patch by Etsuro Fujita. Heavily
refactored by me. Then worked over some more by Amit Langote.

It turns out that old Perl versions (before about 5.10) don't have any
very reliable way to generate Inf or NaN numeric values. Getting around
that would require way more work than is really justified to test the
code involved, so let's just drop these new test cases.

jsonb uses numeric internally, and numeric can store NaN, but that is
not allowed by jsonb on input, so we shouldn't store it. Also prevent
infinity to get a consistent error message. (numeric input would reject
infinity anyway.)

When bt_index_parent_check() is called with the heapallindexed option,
allocate a second Bloom filter to fingerprint block numbers that appear
in the downlinks of internal pages. Use Bloom filter probes when
walking the B-Tree to detect missing downlinks. This can detect subtle
problems with page deletion/VACUUM, such as corruption caused by the bug
just fixed in commit 6db4b499.
The downlink Bloom filter is bound in size by work_mem. Its optimal
size is typically far smaller than that of the regular heapallindexed
Bloom filter, especially when the index has high fan-out.

On further reflection, commit e5d83995e didn't go far enough: pretty much
everywhere in the planner that examines a clause's is_pushed_down flag
ought to be changed to use the more complicated behavior where we also
check the clause's required_relids. Otherwise we could make incorrect
decisions about whether, say, a clause is safe to use as a hash clause.
Some (many?) of these places are safe as-is, either because they are
never reached while considering a parameterized path, or because there
are additional checks that would reject a pushed-down clause anyway.
However, it seems smarter to just code them all the same way rather
than rely on easily-broken reasoning of that sort.
In support of that, invent a new macro RINFO_IS_PUSHED_DOWN that should
be used in place of direct tests on the is_pushed_down flag.
Like the previous patch, back-patch to all supported branches.

Add several assertions that ensure that we're dealing with a pivot tuple
without non-key attributes where that's expected. Also, remove the
assertion within _bt_isequal(), restoring the v10 function signature. A
similar check will be performed for the page highkey within
_bt_moveright() in most cases. Also avoid dropping all objects within
regression tests, to increase pg_dump test coverage for INCLUDE indexes.
Rather than using infrastructure that's generally intended to be used
with reference counted heap tuple descriptors during truncation, use the
same function that was introduced to store flat TupleDescs in shared
memory (we use a temp palloc'd buffer). This isn't strictly necessary,
but seems more future-proof than the old approach. It also lets us
avoid including rel.h within indextuple.c, which was arguably a
modularity violation. Also, we now call index_deform_tuple() with the
truncated TupleDesc, not the source TupleDesc, since that's more robust,
and saves a few cycles.
In passing, fix a memory leak by pfree'ing truncated pivot tuple memory
during CREATE INDEX. Also pfree during a page split, just to be
consistent.
Refactor _bt_check_natts() to be more readable.

Spelling access(2)'s second argument as "2" is just horrid.
POSIX makes no promises as to the numeric values of W_OK and related
macros. Even if it accidentally works as intended on every supported
platform, it's still unreadable and inconsistent with adjacent code.
In passing, don't spell "NULL" as "0" either. Yes, that's legal C;
no, it's not project style.
Back-patch, just in case the unportability is real and not theoretical.
(Most likely, even if a platform had different bit assignments for
access()'s modes, there'd not be an observable behavior difference
here; but I'm being paranoid today.)

There's been a massive addition of partitioning code in PostgreSQL 11,
with little oversight on its placement, resulting in a
catalog/partition.c with poorly defined boundaries and responsibilities.
This commit tries to set a couple of distinct modules to separate things
a little bit. There are no code changes here, only code movement.
There are three new files:
src/backend/utils/cache/partcache.c
src/include/partitioning/partdefs.h
src/include/utils/partcache.h
The previous arrangement of #including catalog/partition.h almost
everywhere is no more.

We've made multiple attempts to stabilize the plans shown by commit
1bc0100d2, with little success so far. The reason for the remaining
instability seems to be that if a transaction (such as auto-analyze)
is running concurrently with the test, then get_actual_variable_range may
return a maximum value for "T 1"."C 1" that's far away from the actual max,
as a result of our having transiently inserted such a value earlier in
the test. Because we use a non-MVCC snapshot to fetch the value (for
performance reasons), the presence of other transactions can cause that
function to return entries that are actually dead.
To fix, use a less extreme value in the earlier transient insertion, so
that whether it is visible or not won't affect the selectivity estimate.
The use of 9999 there seems to have been picked with the aid of a
dartboard anyway, rather than having a specific reason.

This reverts commits d204ef63776b8a00ca220adec23979091564e465,
83454e3c2b28141c0db01c7d2027e01040df5249 and a few more commits thereafter
(complete list at the end) related to MERGE feature.
While the feature was fully functional, with sufficient test coverage and
necessary documentation, it was felt that some parts of the executor and
parse-analyzer can use a different design and it wasn't possible to do that in
the available time. So it was decided to revert the patch for PG11 and retry
again in the future.

In commit 9c0a0de4c, I'd failed to notice that catalog/catalog.h
should also be considered a frontend-unsafe header, because it includes
(and needs) the full form of pg_class.h, not to mention relcache.h.
However, various frontend code was depending on it to get
TABLESPACE_VERSION_DIRECTORY, so refactoring of some sort is called for.
The cleanest answer seems to be to move TABLESPACE_VERSION_DIRECTORY,
as well as the OIDCHARS symbol, to common/relpath.h. Do that, and mop up
inclusions as necessary. (I found that quite a few current users of
catalog/catalog.h don't seem to need it at all anymore, apparently as a
result of the refactorings that created common/relpath.[hc]. And
initdb.c needed it only as a route to pg_class_d.h.)

Repeating these tests adds unnecessary cycles, since no improvement in
test coverage is expected.

Traditionally, include/catalog/pg_foo.h contains extern declarations
for functions in backend/catalog/pg_foo.c, in addition to its function
as the authoritative definition of the pg_foo catalog's rowtype.
In some cases, we'd been forced to split out those extern declarations
into separate pg_foo_fn.h headers so that the catalog definitions
could be #include'd by frontend code. That problem is gone as of
commit 9c0a0de4c, so let's undo the splits to make things less
confusing.

Everything of use to frontend code should now appear in the _d.h files,
and making this change frees us from needing to worry about whether the
catalog header files proper are frontend-safe.
Remove src/interfaces/ecpg/ecpglib/pg_type.h entirely, as the previous
commit reduced it to a confusingly-named wrapper around pg_type_d.h.
In passing, make test_rls_hooks.c follow project convention of including
our own files with #include "" not <>.

This patch introduces INCLUDE clause to index definition. This clause
specifies a list of columns which will be included as a non-key part in
the index. The INCLUDE columns exist solely to allow more queries to
benefit from index-only scans. Also, such columns don't need to have
appropriate operator classes. Expressions are not supported as INCLUDE
columns since they cannot be used in index-only scans.
Index access methods supporting INCLUDE are indicated by amcaninclude flag
in IndexAmRoutine. For now, only B-tree indexes support INCLUDE clause.
In B-tree indexes INCLUDE columns are truncated from pivot index tuples
(tuples located in non-leaf pages and high keys). Therefore, B-tree indexes
now might have variable number of attributes. This patch also provides
generic facility to support that: pivot tuples contain number of their
attributes in t_tid.ip_posid. Free 13th bit of t_info is used for indicating
that. This facility will simplify further support of index suffix truncation.
The changes of above are backward-compatible, pg_upgrade doesn't need special
handling of B-tree indexes for that.

This provides a newer version of adminpack which works with the newly
added default roles to support GRANT'ing to non-superusers access to
read and write files, along with related functions (unlinking files,
getting file length, renaming/removing files, scanning the log file
directory) which are supported through adminpack.
Note that new versions of the functions are required because an
environment might have an updated version of the library but still have
the old adminpack 1.0 catalog definitions (where EXECUTE is GRANT'd to
PUBLIC for the functions).
This patch also removes the long-deprecated alternative names for
functions that adminpack used to include and which are now included in
the backend, in adminpack v1.1. Applications using the deprecated names
should be updated to use the backend functions instead. Existing
installations which continue to use adminpack v1.0 should continue to
function until/unless adminpack is upgraded.

This patch adds new default roles named 'pg_read_server_files',
'pg_write_server_files', 'pg_execute_server_program' which
allow an administrator to GRANT to a non-superuser role the ability to
access server-side files or run programs through PostgreSQL (as the user
the database is running as). Having one of these roles allows a
non-superuser to use server-side COPY to read, write, or with a program,
and to use file_fdw (if installed by a superuser and GRANT'd USAGE on
it) to read from files or run a program.
The existing misc file functions are also changed to allow a user with
the 'pg_read_server_files' default role to read any files on the
filesystem, matching the privileges given to that role through COPY and
file_fdw from above.

BGWORKER_BYPASS_ALLOWCONN, is defined, which allows the worker to ignore
