* Remove a confusing pair of parentheses.Neil Conway2006-01-11

* Improve error messages for missing-FROM-entry cases, as per recent discussion.Tom Lane2006-01-10

* Minor code clarity improvement: AFAICS, estate.eval_econtext must beNeil Conway2006-01-10
| | | | | | non-NULL during the guts of plpgsql_exec_trigger() and plpgsql_exec_function(). Therefore, we can remove the NULL check, per discussion on -patches.
* Improve patternsel() by applying the operator itself to each valueTom Lane2006-01-10
| | | | | | | | | listed in the column's most-common-values statistics entry. This gives us an exact selectivity result for the portion of the column population represented by the MCV list, which can be a big leg up in accuracy if that's a large fraction of the population. The heuristics involving pattern contents and prefix are applied only to the part of the population not included in the MCV list.
* remove unneeded defines for uid_t and gid_t, which conflict with perl's ↵Andrew Dunstan2006-01-10
| | | | typedefs.
* In PLy_function_build_args(), the code loops repeatedly, constructingNeil Conway2006-01-10
| | | | | | | | | | | | | | | | one argument at a time and then inserting the argument into a Python list via PyList_SetItem(). This "steals" the reference to the argument: that is, the reference to the new list member is now held by the Python list itself. This works fine, except if an elog occurs. This causes the function's PG_CATCH() block to be invoked, which decrements the reference counts on both the current argument and the list of arguments. If the elog happens to occur during the second or subsequent iteration of the loop, the reference count on the current argument will be decremented twice. The fix is simple: set the local pointer to the current argument to NULL immediately after adding it to the argument list. This ensures that the Py_XDECREF() in the PG_CATCH() block doesn't double-decrement.
* Fix pg_dump to add the required OPERATOR() decoration to schema-qualifiedTom Lane2006-01-09
| | | | | | operator names. This is needed when dumping operator definitions that have COMMUTATOR (or similar) links to operators in other schemas. Apparently Daniel Whitter is the first person ever to try this :-(
* Change allow_system_table_mods to PGC_POSTMASTER, restoring previousPeter Eisentraut2006-01-09
| | | | behavior.
* Minor code cleanup for PL/Python: fixup some strangely formatted comments,Neil Conway2006-01-09
| | | | | and change two elogs into ereports because they could actually occur in practice.
* Rationalise perl header inclusions via a common include file, which alsoAndrew Dunstan2006-01-08
| | | | | | declares routines in plperl.c and spi_internal.c used in other files. Along the way, also stop perl from hijacking stdio and other stuff on Windows.
* Fix the assert_enabled issue properly. This eliminates the former ABITom Lane2006-01-08
| | | | | difference between USE_ASSERT_CHECKING and not: the assert_enabled variable is always there.
* Recent patch broke guc.c for non-USE_ASSERT_CHECKING case. PerTom Lane2006-01-08
| | | | Stefan Kaltenbrunner.
* Avoid leaking memory while reading toasted entries from pg_rewrite,Tom Lane2006-01-08
| | | | | | | and nail a couple more system indexes into cache. This doesn't make any difference in normal system operation, but when forcing constant cache resets it's difficult to get through the rules regression test without these changes.
* Add a new system view, pg_prepared_statements, that can be used toNeil Conway2006-01-08
| | | | | | | | | | | | | | | | access information about the prepared statements that are available in the current session. Original patch from Joachim Wieland, various improvements by Neil Conway. The "statement" column of the view contains the literal query string sent by the client, without any rewriting or pretty printing. This means that prepared statements created via SQL will be prefixed with "PREPARE ... AS ", whereas those prepared via the FE/BE protocol will not. That is unfortunate, but discussion on -patches did not yield an efficient way to improve this, and there is some merit in returning exactly what the client sent to the backend. Catalog version bumped, regression tests updated.
* Add RelationOpenSmgr() calls to ensure rd_smgr is valid when we try toTom Lane2006-01-07
| | | | | | use it. While it normally has been opened earlier during btree index build, testing shows that it's possible for the link to be closed again if an sinval reset occurs while the index is being built.
* Add comment explaining why RelationOpenSmgr() call is not needed.Tom Lane2006-01-07

* During CatCacheRemoveCList, we must now remove any members that areTom Lane2006-01-07
| | | | | | | | | dead and have become unreferenced. Before 8.1, such members were left for AtEOXact_CatCache() to clean up, but now AtEOXact_CatCache isn't supposed to have anything to do. In an assert-enabled build this bug leads to an assertion failure at transaction end, but in a non-assert build the dead member is effectively just a small memory leak. Per report from Jeremy Drake.
* Fix failure to apply domain constraints to a NULL constant that's added toTom Lane2006-01-06
| | | | an INSERT target list during rule rewriting. Per report from John Supplee.
* Use RELKIND_COMPOSITE_TYPE rather than hardcoded 'c'.Bruce Momjian2006-01-06
|
* Fix Windows-only postmaster code to reject a connection request and continue,Tom Lane2006-01-06
| | | | | | | rather than elog(FATAL), when there is no more room in ShmemBackendArray. This is a security issue since too many connection requests arriving close together could cause the postmaster to shut down, resulting in denial of service. Reported by Yoshiyuki Asaba, fixed by Magnus Hagander.
* Convert Assert checking for empty page into a regular test and elog.Tom Lane2006-01-06
| | | | | The consequences of overwriting a non-empty page are bad enough that we should not omit this test in production builds.
* Fix ReadBuffer() to correctly handle the case where it's trying to extendTom Lane2006-01-06
| | | | | | | | | the relation but it finds a pre-existing valid buffer. The buffer does not correspond to any page known to the kernel, so we *must* do smgrextend to ensure that the space becomes allocated. The 7.x branches all do this correctly, but the corner case got lost somewhere during 8.0 bufmgr rewrites. (My fault no doubt :-( ... I think I assumed that such a buffer must be not-BM_VALID, which is not so.)
* Update x86 Solaris documenation ideas.Bruce Momjian2006-01-05
|
* Add compile flags sample.Bruce Momjian2006-01-05

* Make all command-line options of postmaster and postgres the same. SeePeter Eisentraut2006-01-05
| | | | | http://archives.postgresql.org/pgsql-hackers/2006-01/msg00151.php for the complete plan.

* Rearrange backend startup sequence so that ShmemIndexLock can becomeTom Lane2006-01-04
| | | | | | an LWLock instead of a spinlock. This hardly matters on Unix machines but should improve startup performance on Windows (or any port using EXEC_BACKEND). Per previous discussion.
* Fix another case in which autovacuum would fail while analyzingTom Lane2006-01-04
| | | | expressional indexes. Per report from Brian Hirt.
* Fix incorrect treatment of RL_PROMPT_START_IGNORE/RL_PROMPT_END_IGNORE,Tom Lane2006-01-03
| | | | per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=343616 via Martin Pitt.
* Add checks to verify that a plpgsql function returning a rowtype is actuallyTom Lane2006-01-03
| | | | | returning the rowtype it's supposed to return. Per reports from David Niblett and Michael Fuhr.
* Assume select() might modify struct timeout, so remove previousBruce Momjian2006-01-03
| | | | optimization.
* Use setitimer() for stats file write, rather than do a gettimeofday()Bruce Momjian2006-01-03
| | | | | call for every stats packet read to adjust select() timeout. Other stylistic improvements.
* Don't assume that LC_MESSAGES is always available on WIN32. Per Magnus.Tom Lane2006-01-02

* Reset flex state in a way that works for both flex 2.5.4 and 2.5.31.Tom Lane2006-01-02

* Remove the nexus between trial_buffs and trial_conns, and don't test shared ↵Andrew Dunstan2006-01-02
| | | | buffers lower than or equal to a value we already know is good, but use that value instead. This will make it easier to adjust the trial values and/or formulae in future if necessary.
* Remove unnecessary assignment, per Tom.Bruce Momjian2006-01-02
|
* Change if (!(x || y)) construct with if (!x && !y), for clarity.Bruce Momjian2006-01-02
|
* Rewrite ProcessConfigFile() to avoid misbehavior at EOF, as per reportTom Lane2006-01-01
| | | | | | | | from Andrus Moor. The former state-machine-style coding wasn't actually doing much except obscuring the control flow, and it didn't extend readily to fix this case, so I just took it out. Also, add a YY_FLUSH_BUFFER call to ensure the lexer is reset correctly if the previous scan failed partway through the file.
* Remove DOS line endings ("\r\n") from several .po files. DOS line endingsNeil Conway2006-01-01
| | | | | are inconsistent with the rest of the .po files, and apparently cause problems for Sun's cc. Per report on IRC from "bitvector2".
* Trim an obsolete comment: it is no longer relevant that "SELECT" wasNeil Conway2006-01-01
| | | | formerly "RETRIEVE", and so forth.
* Clean up initdb's code for selecting max_connections and shared_buffersTom Lane2005-12-31
| | | | | | | | | a little bit, and set the minimum buffers-per-connection ratio to 10 not 5. I folded the two test routines into one to counteract the illusion that the tests can be twiddled independently, and added some documentation pointing out the necessary connection between the sets of values tested. Fixes strange choices of parameters that I noticed CVS tip making on Darwin with Apple's undersized default SHMMAX.

| | | | | | selection of a field from the result of a function returning RECORD. I believe this case is new in 8.1; it's due to the addition of OUT parameters. Per example from Michael Fuhr.
