* When we added the ability to have zero-element ARRAY[] constructs by adding anTom Lane2008-12-19
| | | | | | explicit cast to show the intended array type, we forgot to teach ruleutils.c to print out such constructs properly. Found by noting bogus output from recent changes in polymorphism regression test.
* Add a couple of cross-references to the docs about enum types, per aTom Lane2008-12-19
| | | | recent gripe that the info is hard to find.
* Add "not" to wal journaling text.Bruce Momjian2008-12-18

* Fix oversight in my recent patch to allow ExecMakeFunctionResult to handleTom Lane2008-12-18
| | | | | | | materialize-mode set results. Since it now uses the ReturnSetInfo node to hold internal state, we need to be sure to set up the node even when the immediately called function doesn't return set (but does have a set-valued argument). Per report from Anupama Aherrao.
* Code review for function default parameters patch. Fix numerous problems asTom Lane2008-12-18
| | | | | per recent discussions. In passing this also fixes a couple of bugs in the previous variadic-parameters patch.
* Update documentation table describing how shared memory is used byBruce Momjian2008-12-18

* Add note that TRUNCATE uses an access exclusive lock. This apparentlyPeter Eisentraut2008-12-18

* Don't reset pg_class.reltuples and relpages in VACUUM, if any pages wereHeikki Linnakangas2008-12-17
| | | | | | | | | | | | | | | | | skipped. We could update relpages anyway, but it seems better to only update it together with reltuples, because we use the reltuples/relpages ratio in the planner. Also don't update n_live_tuples in pgstat. ANALYZE in VACUUM ANALYZE now needs to update pg_class, if the VACUUM-phase didn't do so. Added some boolean-passing to let analyze_rel know if it should update pg_class or not. I also moved the relcache invalidation (to update rd_targblock) from vac_update_relstats to where RelationTruncate is called, because vac_update_relstats is not called for partial vacuums anymore. It's more obvious to send the invalidation close to the truncation that requires it. Per report by Ned T. Crigler.
* The attached patch contains a couple of fixes in the existing probes andBruce Momjian2008-12-17
| | | | | | | | | | | | | includes a few new ones. - Fixed compilation errors on OS X for probes that use typedefs - Fixed a number of probes to pass ForkNumber per the relation forks patch - The new probes are those that were taken out from the previous submitted patch and required simple fixes. Will submit the other probes that may require more discussion in a separate patch. Robert Lor
* Add note to the shared memory sizing table about needing to use page count inAlvaro Herrera2008-12-16
| | | | shared_buffers and wal_buffers, not size in bytes. Per discussion.
* Make heap_update() set newtup->t_tableOid correctly, for consistency withTom Lane2008-12-16
| | | | | | | | | | the other major heapam.c functions. The only known consequence of this omission is that UPDATE RETURNING failed to return the correct value for "tableoid", as per report from KaiGai Kohei. Back-patch to 8.2. Arguably it's wrong all the way back; but without evidence of visible breakage before RETURNING was added, I'll desist from patching the older branches.

* Department of second thoughts: further experimentation with CREATE OR REPLACETom Lane2008-12-16
| | | | | VIEW suggests that it'd be worth spelling the error messages out in a little more detail. This seems to help with localizing the problem.

| | | | | result in hopefully-less-confusing error messages when the new definition isn't compatible with the old; minor other cleanup.

* Fix cast-away-const problem as well as bogus calculation of required buffer ↵Tom Lane2008-12-15
| | | | size.
* Arrange for the pg_foo_is_visible and has_foo_privilege families of functionsTom Lane2008-12-15
| | | | | | | | | | | to return NULL, instead of erroring out, if the target object is specified by OID and we can't find that OID in the catalogs. Since these functions operate internally on SnapshotNow rules, there is a race condition when using them in user queries: the query's MVCC snapshot might "see" a catalog row that's already committed dead, leading to a failure when the inquiry function is applied. Returning NULL should generally provide more convenient behavior. This issue has been complained of before, and in particular we are now seeing it in the regression tests due to another recent patch.
* Do not try to change a const variable.Michael Meskes2008-12-15

* Reduce the scaling factor for attstattarget to number-of-lexemes from 100Tom Lane2008-12-15
| | | | | | | to 10, to compensate for the recent change in default statistics target. The original number was pulled out of the air anyway :-(, but it was picked in the context of the old default, so holding the default size of the MCELEM array constant seems the best thing. Per discussion.
* Remove our dependencies on MB_CUR_MAX in favor of believing thatTom Lane2008-12-15
| | | | | | | | | | pg_database_encoding_max_length() predicts the maximum character length returned by wchar2char(). Per Hiroshi Inoue, MB_CUR_MAX isn't usable on Windows because we allow encoding = UTF8 when the locale says differently; and getting rid of it seems a good idea on general principles because it narrows our dependence on libc's locale API just a little bit more. Also install a check for overflow of the buffer size computation.
* Support specifying filename for SSL certificate, key, root certificate storeMagnus Hagander2008-12-15
| | | | | | | | and certificate revokation list by using connection parameters or environment variables. Original patch by Mark Woodward, heavily reworked by Alvaro Herrera and Magnus Hagander.
* Restore enforce_generic_type_consistency's pre-8.3 behavior of allowing anTom Lane2008-12-14
| | | | | | | actual argument type of ANYARRAY to match an argument declared ANYARRAY, so long as ANYELEMENT etc aren't used. I had overlooked the fact that this is a possible case while fixing bug #3852; but it is possible because pg_statistic contains columns declared ANYARRAY. Per gripe from Corey Horton.
* Replace both send and receive BIO routines in the SSL code with our own,Magnus Hagander2008-12-14
| | | | | calling recv() and send(). This makes the calls go through the socket emulation code on Win32, making them for example properly interruptible.
* Increase the default value of default_statistics_target from 10 to 100,Tom Lane2008-12-13
| | | | | and its maximum value from 1000 to 10000. ALTER TABLE SET STATISTICS similarly now allows a value up to 10000. Per discussion.
* Remove pg_plan_queries()'s now-useless needSnapshot parameter. It's uselessTom Lane2008-12-13
| | | | | in 8.3, too, but I'm not back-patching this change since it would break any extension modules that might be calling that function.
* Fix failure to ensure that a snapshot is available to datatype input functionsTom Lane2008-12-13
| | | | | | | | | | | | | | | | | | | when they are invoked by the parser. We had been setting up a snapshot at plan time but really it needs to be done earlier, before parse analysis. Per report from Dmitry Koterov. Also fix two related problems discovered while poking at this one: exec_bind_message called datatype input functions without establishing a snapshot, and SET CONSTRAINTS IMMEDIATE could call trigger functions without establishing a snapshot. Backpatch to 8.2. The underlying problem goes much further back, but it is masked in 8.1 and before because we didn't attempt to invoke domain check constraints within datatype input. It would only be exposed if a C-language datatype input function used the snapshot; which evidently none do, or we'd have heard complaints sooner. Since this code has changed a lot over time, a back-patch is hardly risk-free, and so I'm disinclined to patch further than absolutely necessary.

* To reduce confusion over whether VACUUM FULL is needed for anti-wraparoundTom Lane2008-12-11
| | | | | | vacuuming (it's not), say "database-wide VACUUM" instead of "full-database VACUUM" in the relevant hint messages. Also, document the permissions needed to do this. Per today's discussion.
* The macros NULL_DEV and DEVNULL were both used to work aroundPeter Eisentraut2008-12-11
| | | | | platform-specific spellings of /dev/null. But one should be enough, so settle on DEVNULL.
* Move carefully obscured SunOS 4 specific #include out of c.h into portPeter Eisentraut2008-12-11
| | | | | header file. SunOS 4 is probably broken anyway, but this item stuck out as completely weird.
* Append major version number and for libraries soname major version numberPeter Eisentraut2008-12-11
| | | | | | | to the gettext domain name, to simplify parallel installations. Also, rename set_text_domain() to pg_bindtextdomain(), because that is what it does.
* Tweak the tree descent loop in fsm_search_avail to not look at theTom Lane2008-12-10
| | | | | | right child if it doesn't need to. This saves some miniscule number of cycles, but the ulterior motive is to avoid an optimization bug known to exist in SCO's C compiler (and perhaps others?)

|
* Provide support for multiplexing SIGUSR1 signal. The upcoming synchronousHeikki Linnakangas2008-12-09
| | | | | | replication patch needs a signal, but we've already used SIGUSR1 and SIGUSR2 in normal backends. This patch allows reusing SIGUSR1 for that, and for other purposes too if the need arises.
* Clearify how processes are started by autovacuum, and what the effectMagnus Hagander2008-12-08
| | | | | | of autovacuum_max_workers parameter is. Per discussion with Alvaro.
* Teach pgstat_vacuum_stat to not bother scanning pg_proc in the common caseTom Lane2008-12-08
| | | | | | where no function stats entries exist. Partial response to Pavel's observation that small VACUUM operations are noticeably slower in CVS HEAD than 8.3.
* Add note that autovacuum can use up several times maintenance_work_mem,Magnus Hagander2008-12-08
| | | | with warning against setting it too high.
* Don't try to optimize EXISTS subqueries with empty FROM-lists: we need toTom Lane2008-12-08
| | | | | | form a join and that case doesn't have anything to join to. (We could probably make it work if we didn't pull up the subquery, but it seems to me that the case isn't worth extra code.) Per report from Greg Stark.
