* Don't use a duplicate OID for aclexplode().Tom Lane2009-12-06

* Speed up information schema privilege viewsPeter Eisentraut2009-12-05
| | | | | | | | | | | | | Instead of expensive cross joins to resolve the ACL, add table-returning function aclexplode() that expands the ACL into a useful form, and join against that. Also, implement the role_*_grants views as a thin layer over the respective *_privileges views instead of essentially repeating the same code twice. fixes bug #4596 by Joachim Wieland, with cleanup by me
* Fix bug in temporary file management with subtransactions. A cursor openedHeikki Linnakangas2009-12-03
| | | | | | | | | | | | | in a subtransaction stays open even if the subtransaction is aborted, so any temporary files related to it must stay alive as well. With the patch, we use ResourceOwners to track open temporary files and don't automatically close them at subtransaction end (though in the normal case temporary files are registered with the subtransaction resource owner and will therefore be closed). At end of top transaction, we still check that there's no temporary files marked as close-at-end-of-transaction open, but that's now just a debugging cross-check as the resource owner cleanup should've closed them already.
* thread-safetyBruce Momjian2009-12-02
| | | | Apply full patch to enable thread-safety by default, e.g. doc changes.
* Mark application_name as GUC_REPORT so that the value will be reported backTom Lane2009-12-02
| | | | | | | | to the client by the server. This might seem pretty pointless but apparently it will help pgbouncer, and perhaps other connection poolers. Anyway it's practically free to do so for the normal use-case where appname is only set in the startup packet --- we're just adding a few more bytes to the initial ParameterStatus response packet. Per comments from Marko Kreen.
* Instead of sending application_name as a SET command after the connectionTom Lane2009-12-02
| | | | | | | | | | | is made, include it in the startup-packet options. This makes it work more like every other libpq connection option, in particular it now has the same response to RESET ALL as the rest. This also saves one network round trip for new applications using application_name. The cost is that if the server is pre-8.5, it'll reject the startup packet altogether, forcing us to retry the entire connection cycle. But on balance we shouldn't be optimizing that case in preference to the behavior with a new server, especially when doing so creates visible behavioral oddities. Per discussion.
* psql -f -Bruce Momjian2009-12-01
| | | | | | Adjust psql -f - to behave like a normal file and honor the -1 flag. Report from Robert Haas
* Teach the regular expression functions to do case-insensitive matching andTom Lane2009-12-01
| | | | | | | | | | | | | | | | | | | | locale-dependent character classification properly when the database encoding is UTF8. The previous coding worked okay in single-byte encodings, or in any case for ASCII characters, but failed entirely on multibyte characters. The fix assumes that the <wctype.h> functions use Unicode code points as the wchar representation for Unicode, ie, wchar matches pg_wchar. This is only a partial solution, since we're still stupid about non-ASCII characters in multibyte encodings other than UTF8. The practical effect of that is limited, however, since those cases are generally Far Eastern glyphs for which concepts like case-folding don't apply anyway. Certainly all or nearly all of the field reports of problems have been about UTF8. A more general solution would require switching to the platform's wchar representation for all regex operations; which is possible but would have substantial disadvantages. Let's try this and see if it's sufficient in practice.

* Fix session-lifespan memory leak when a plperl function is redefined:Tom Lane2009-11-29
| | | | | | | | we have to tell Perl it can release its compiled copy of the function text. Noted by Alexey Klyukin. Back-patch to 8.2 --- the problem exists further back, but this patch won't work without modification, and it's probably not worth the trouble.

* Add some opr_sanity checks that the lengths of the various argument-infoTom Lane2009-11-29

* Eliminate a lot of list-management overhead within join_search_one_levelTom Lane2009-11-28
| | | | | | | | | | | | | | by adding a requirement that build_join_rel add new join RelOptInfos to the appropriate list immediately at creation. Per report from Robert Haas, the list_concat_unique_ptr() calls that this change eliminates were taking the lion's share of the runtime in larger join problems. This doesn't do anything to fix the fundamental combinatorial explosion in large join problems, but it should push out the threshold of pain a bit further. Note: because this changes the order in which joinrel lists are built, it might result in changes in selected plans in cases where different alternatives have exactly the same costs. There is one example in the regression tests.

* Fix an old bug in multixact and two-phase commit. Prepared transactions canHeikki Linnakangas2009-11-23
| | | | | | | | | | | | | be part of multixacts, so allocate a slot for each prepared transaction in the "oldest member" array in multixact.c. On PREPARE TRANSACTION, transfer the oldest member value from the current backends slot to the prepared xact slot. Also save and recover the value from the 2pc state file. The symptom of the bug was that after a transaction prepared, a shared lock still held by the prepared transaction was sometimes ignored by other transactions. Fix back to 8.1, where both 2PC and multixact were introduced.
* Adjust expected-results spacing per buildfarm results.Tom Lane2009-11-22

* Remove -w (--ignore-all-space) option from pg_regress's diff calls.Tom Lane2009-11-22
| | | | | | | | | | | | | We have used -w for a long time as a means of reducing the reported diff volume when one element of a result table isn't of the expected width. However, most of the time the results just pass anyway, so this isn't as important as it once was. Meanwhile, the risk of missing potentially significant deviations has gone up, particularly with psql's ability to report error cursor positions. So, let's switch over to space-sensitive comparisons. Per my proposal of yesterday. (All the expected files that I can test here seem to be ready for this already, but we'll see what the buildfarm thinks about others.)

* Improve psql's tabular display of wrapped-around data by inserting markersTom Lane2009-11-22
| | | | | | | | | | | | | | | | in the formerly-always-blank columns just to left and right of the data. Different marking is used for a line break caused by a newline in the data than for a straight wraparound. A newline break is signaled by a "+" in the right margin column in ASCII mode, or a carriage return arrow in UNICODE mode. Wraparound is signaled by a dot in the right margin as well as the following left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE mode. "\pset linestyle old-ascii" is added to make the previous behavior available if anyone really wants it. In passing, this commit also cleans up a few regression test files that had unintended spacing differences from the current actual output. Roger Leigh, reviewed by Gabrielle Roth and other members of PDXPUG.

| | | | | | | | | | | list, minus a few specific words that have to be treated specially. This replaces a hard-wired list of keywords that would have needed manual maintenance, and was not getting it. The 8.4 coding was already missing these words, causing ecpg to incorrectly treat them as reserved words: CALLED, CATALOG, DEFINER, ENUM, FOLLOWING, INVOKER, OPTIONS, PARTITION, PRECEDING, RANGE, SECURITY, SERVER, UNBOUNDED, WRAPPER. In HEAD we were additionally missing COMMENTS, FUNCTIONS, SEQUENCES, TABLES. Per gripe from Bosco Rama.
* Add a WHEN clause to CREATE TRIGGER, allowing a boolean expression to beTom Lane2009-11-20
| | | | | | | | | | | checked to determine whether the trigger should be fired. For BEFORE triggers this is mostly a matter of spec compliance; but for AFTER triggers it can provide a noticeable performance improvement, since queuing of a deferred trigger event and re-fetching of the row(s) at end of statement can be short-circuited if the trigger does not need to be fired.

| | | | | | | | | output filename if CSV logging was enabled and only one of the two possible output files got rotated during a particular call (which would, in fact, typically be the case during a size-based rotation). This would amount to about MAXPGPATH (1KB) per rotation, and it's been there since the CSV code was put in, so it's surprising that nobody noticed it before. Per bug #5196 from Thomas Poindessous.

* While doing the final setrefs.c pass over a plan tree, try to match upTom Lane2009-11-16
| | | | | | | | | | | | | | | non-Var sort/group expressions using ressortgroupref labels instead of depending entirely on equal()-ity of the upper node's tlist expressions to the lower node's. This avoids emitting the wrong outputs in cases where there are textually identical volatile sort/group expressions, as for example select distinct random(),random() from generate_series(1,10); Per report from Andrew Gierth. Backpatch to 8.4. Arguably this is wrong all the way back, but the only known case where there's an observable problem is when using hash aggregation to implement DISTINCT, which is new as of 8.4. So for the moment I'll refrain from backpatching further.

| | | | | | | | | mergejoin to shield it from doing mark/restore and refetches. Put an explicit flag in MergePath so we can centralize the logic that knows about this, and add costing logic that considers using Materialize even when it's not forced by the previously-existing considerations. This is in response to a discussion back in August that suggested that materializing an inner indexscan can be helpful when the refetch percentage is high enough.
