* Add SPI-level support for executing SQL commands with one-time-use plans,Tom Lane2008-04-01
| | | | | | | | | | | that is commands that have out-of-line parameters but the plan is prepared assuming that the parameter values are constants. This is needed for the plpgsql EXECUTE USING patch, but will probably have use elsewhere. This commit includes the SPI functions and documentation, but no callers nor regression tests. The upcoming EXECUTE USING patch will provide regression-test coverage. I thought committing this separately made sense since it's logically a distinct feature.
* Fix an oversight I made in a cleanup patch over a year ago:Tom Lane2008-04-01
| | | | | | | | | | eval_const_expressions needs to be passed the PlannerInfo ("root") structure, because in some cases we want it to substitute values for Param nodes. (So "constant" is not so constant as all that ...) This mistake partially disabled optimization of unnamed extended-Query statements in 8.3: in particular the LIKE-to-indexscan optimization would never be applied if the LIKE pattern was passed as a parameter, and constraint exclusion depending on a parameter value didn't work either.
* Apply my original fix for Taiki Yamaguchi's bug report about DISTINCT MAX().Tom Lane2008-03-31
| | | | Add some regression tests for plausible failures in this area.
* Fix my brain fade in TRUNCATE triggers patch: can't release relcache refcountsTom Lane2008-03-31
| | | | | | while EState still contains pointers to those relations. Exposed by the CLOBBER_CACHE_ALWAYS tests that buildfarm member jaguar is running (I knew those cycles would pay off...)
* Use error message wordings for permissions checks on .pgpass and SSL privateTom Lane2008-03-31
| | | | | | | | | | | | key files that are similar to the one for the postmaster's data directory permissions check. (I chose to standardize on that one since it's the most heavily used and presumably best-wordsmithed by now.) Also eliminate explicit tests on file ownership in these places, since the ensuing read attempt must fail anyway if it's wrong, and there seems no value in issuing the same error message for distinct problems. (But I left in the explicit ownership test in postmaster.c, since it had its own error message anyway.) Also be more specific in the documentation's descriptions of these checks. Per a gripe from Kevin Hunter.
* Fix a number of places that were making file-type tests infelicitously.Tom Lane2008-03-31
| | | | | | | | | | | | | | | | | The places that did, eg, (statbuf.st_mode & S_IFMT) == S_IFDIR were correct, but there is no good reason not to use S_ISDIR() instead, especially when that's what the other 90% of our code does. The places that did, eg, (statbuf.st_mode & S_IFDIR) were flat out *wrong* and would fail in various platform-specific ways, eg a symlink could be mistaken for a regular file on most Unixen. The actual impact of this is probably small, since the problem cases seem to always involve symlinks or sockets, which are unlikely to be found in the directories that PG code might be scanning. But it's clearly trouble waiting to happen, so patch all the way back anyway. (There seem to be no occurrences of the mistake in 7.4.)

* Enable 64-bit integer datetimes by default, per previous discussion.Neil Conway2008-03-30
| | | | | | This requires a working 64-bit integer type. If such a type cannot be found, "--disable-integer-datetimes" can be used to switch back to the previous floating point-based datetime implementation.
* Improve description of \du and \dg, per suggestion fromTom Lane2008-03-29

* Improve psql's tab completion to handle completing attribute names in casesTom Lane2008-03-29
| | | | | | | | | | where the relation name was schema-qualified, for example UPDATE foo.bar SET <tab> Also support cases where the relation name was quoted unnecessarily, for example UPDATE "foo" SET <tab> Greg Sabino Mullane, slightly simplified by myself.
* Revert my erroneous fix for Taiki Yamaguchi's DISTINCT MAX() bug.Tom Lane2008-03-29

* Department of second thoughts: the rule that ORDER BY and DISTINCT areTom Lane2008-03-28
| | | | | | | | | useless for an ungrouped-aggregate query holds regardless of whether optimize_minmax_aggregates succeeds. So we might as well apply the optimization in any case. I'll leave 8.3 as it was, since this version is a tad more invasive than my earlier patch.

* When we have successfully optimized a MIN or MAX aggregate into an indexscan,Tom Lane2008-03-27
| | | | | | | | | | the query result must be exactly one row (since we don't do this when there's any GROUP BY). Therefore any ORDER BY or DISTINCT attached to the query is useless and can be dropped. Aside from saving useless cycles, this protects us against problems with matching the hacked-up tlist entries to sort clauses, as seen in a bug report from Taiki Yamaguchi. We might need to work harder if we ever try to optimize grouped queries with this approach, but this solution will do for now.

* Reduce the need for frontend programs to include "postgres.h" by refactoringTom Lane2008-03-27
| | | | | | | | | | | | inclusions in src/include/catalog/*.h files. The main idea here is to push function declarations for src/backend/catalog/*.c files into separate headers, rather than sticking them into the corresponding catalog definition file as has been done in the past. This commit only carries out that idea fully for pg_proc, pg_type and pg_conversion, but that's enough for the moment --- if pg_list.h ever becomes unsafe for frontend code to include, we'll need to work a bit more.

| | | | | | | | | | | | | snapmgmt.c file for the former. The header files have also been reorganized in three parts: the most basic snapshot definitions are now in a new file snapshot.h, and the also new snapmgmt.h keeps the definitions for snapmgmt.c. tqual.h has been reduced to the bare minimum. This patch is just a first step towards managing live snapshots within a transaction; there is no functionality change. Per my proposal to pgsql-patches on 20080318191940.GB27458@alvh.no-ip.org and subsequent discussion.

* Simplify and standardize conversions between TEXT datums and ordinary CTom Lane2008-03-25
| | | | | | | | | | | | | | | | | | | | strings. This patch introduces four support functions cstring_to_text, cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and two macros CStringGetTextDatum and TextDatumGetCString. A number of existing macros that provided variants on these themes were removed. Most of the places that need to make such conversions now require just one function or macro call, in place of the multiple notational layers that used to be needed. There are no longer any direct calls of textout or textin, and we got most of the places that were using handmade conversions via memcpy (there may be a few still lurking, though). This commit doesn't make any serious effort to eliminate transient memory leaks caused by detoasting toasted text objects before they reach text_to_cstring. We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few places where it was easy, but much more could be done. Brendan Jurd and Tom Lane
