* Better error message on character set mismatches during conversion to unicode.Barry Lind2003-02-09
| | | | | | | | | | Also applied patch from Lars Stenberg to make callable statements use the form select * from func() when running against a 7.3 server instead of select func() to allow for set returning functions to be called. Modified Files: jdbc/org/postgresql/errors.properties jdbc/org/postgresql/core/Encoding.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Statement.java
* Create a distinction between Lists of integers and Lists of OIDs, to getTom Lane2003-02-09
| | | | | | rid of the assumption that sizeof(Oid)==sizeof(int). This is one small step towards someday supporting 8-byte OIDs. For the moment, it doesn't do much except get rid of a lot of unsightly casts.
* Remove bogus comment (too freely copied & pasted).Tom Lane2003-02-09

* Make further use of new bitmapset code: executor's chgParam, extParam,Tom Lane2003-02-09
| | | | | | | | locParam lists can be converted to bitmapsets to speed updating. Also, replace 'locParam' with 'allParam', which contains all the paramIDs relevant to the node (i.e., the union of extParam and locParam); this saves a step during SetChangedParamList() without costing anything elsewhere.
* Replace planner's representation of relation sets, per pghackers discussion.Tom Lane2003-02-08
| | | | | Instead of Lists of integers, we now store variable-length bitmap sets. This should be faster as well as less error-prone.

* Revise mechanism for getting rid of temp tables at backend shutdown.Tom Lane2003-02-07
| | | | | | | | | | Instead of grovelling through pg_class to find them, make use of the handy dandy dependency mechanism: just delete everything that depends on our temp schema. Unlike the pg_class scan, the dependency mechanism is smart enough to delete things in an order that doesn't fall foul of any dependency restrictions. Fixes problem reported by David Heggie: a temp table with a serial column may cause a backend FATAL exit at shutdown time, if it chances to try to delete the temp sequence first.
* Make flatten_join_alias_vars() do the right thing when expanding an aliasTom Lane2003-02-06
| | | | referenced from a subquery. Per example from Stefanos Harhalakis.
* Create a GUC variable REGEX_FLAVOR to control the type of regularTom Lane2003-02-06
| | | | | | | | expression accepted by the regex operators, per discussion yesterday. Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP category. It is probably best to insist that all backends share the same setting, but that doesn't mean it has to be frozen at startup.
* Fix core dump when pltcl_elog is called with wrong number of parameters,Tom Lane2003-02-06
| | | | per report from Ian Harding.
* Allow qualified type names in CREATE CAST, DROP CAST. Also allow theTom Lane2003-02-05
| | | | | construction 'SETOF type[]' which for some reason was previously overlooked (you'd have to name the array type directly to make it work).
* Replace regular expression package with Henry Spencer's latest versionTom Lane2003-02-05
| | | | | | | (extracted from Tcl 8.4.1 release, as Henry still hasn't got round to making it a separate library). This solves a performance problem for multibyte, as well as upgrading our regexp support to match recent Tcl and nearly match recent Perl.

* Two patches from Kris Jurka. One fixes a problem with incorrect type for doubleBarry Lind2003-02-04
| | | | | and the other fixes a NPE in Statement.toString() under some circumstances. The second patch was originally submitted by Oliver Jowett and updated by Kris
* Patch from Nic Ferrier to add support for result sets being cursor basedBarry Lind2003-02-04
| | | | | so that rows can be fetched incrementally. This is enabled by using setFetchSize()
* Minor code cleanup: remove no-longer-useful pull_subplans() function,Tom Lane2003-02-04
| | | | | and convert pull_agg_clause() into count_agg_clause(), which is a more efficient way of doing what it's really being used for.
* Detect duplicate aggregate calls and evaluate only one copy. ThisTom Lane2003-02-04
| | | | | speeds up some useful real-world cases like SELECT x, COUNT(*) FROM t GROUP BY x HAVING COUNT(*) > 100.
* #ifdef out stuff that shouldn't be compiled when not USE_SSL.Tom Lane2003-02-03
| | | | Curious that gcc doesn't complain about unreferenced static variables.
* Determine the set of constraints applied to a domain at executorTom Lane2003-02-03
| | | | | | startup, not in the parser; this allows ALTER DOMAIN to work correctly with domain constraint operations stored in rules. Rod Taylor; code review by Tom Lane.
* Don't print NO ACTION foreign key actions in dumps and psql \d.Bruce Momjian2003-02-03
|
* Tweak planner and executor to avoid doing ExecProject() in table scanTom Lane2003-02-03
| | | | | | | | nodes where it's not really necessary. In many cases where the scan node is not the topmost plan node (eg, joins, aggregation), it's possible to just return the table tuple directly instead of generating an intermediate projection tuple. In preliminary testing, this reduced the CPU time needed for 'SELECT COUNT(*) FROM foo' by about 10%.
* Move pg_service.conf.sample to /interfaces/libpq.Bruce Momjian2003-02-03
|
* Change MOVE LAST to MOVE ALL.Bruce Momjian2003-02-03
| | | | Standard says FETCH LAST is after last row, and we don't do that.
* Implement EXPLAIN EXECUTE. By Neil Conway, with some kibitzing fromTom Lane2003-02-02
| | | | Tom Lane.
* Fix nodeUnique to behave correctly when reversing direction after reachingTom Lane2003-02-02
| | | | | either end of subplan results. This prevents misbehavior of cursors on SELECT DISTINCT ... queries. Per bug report 1-Feb-02.
* Remove restriction that cast functions cannot be volatile. ThisTom Lane2003-02-01
| | | | | | restriction was debatable to begin with, but it has now become obvious that it breaks forward-porting of user-defined types; contrib/lo being the most salient example.
* Cleaner solution to the problem of loading pre-7.3 dumps containingTom Lane2003-02-01
| | | | | | columns of type lo (see contrib/lo). Rather than hacking the function definitions on-the-fly, just modify the queries issued by FixupBlobRefs so that they work even if CREATE CAST hasn't been issued.
* Changes of 6-Sep-02 broke pg_restore's ability to recognize tar-formatTom Lane2003-02-01
| | | | files. Fix it.
* Fix assign_session_authorization() to not be confused by all-numericTom Lane2003-02-01
| | | | user names. Per recent reports.
* Prevent core dump from calling Tcl_DontCallWhenDeleted() with a nullTom Lane2003-02-01
| | | | interp pointer. Per report from Gerhard Hintermayer.
* Apply ljb's patch to prevent both memory leak and core dump duringTom Lane2003-02-01
| | | | | | connection shutdown. This is a grotty workaround for a Tcl bug, but said bug has been there long enough that I'm not holding my breath for a real fix. Per discussions and testing from ljb and g.hintermayer.
* Make plpython's spi_execute interface handle NULLs properly.Tom Lane2003-01-31
| | | | From Andrew Bosma.
* Clean up plpython error reporting so that its regression test passesTom Lane2003-01-31
| | | | | with some amount of cleanliness. I see no need to report the internal Python name rather than the SQL procedure name in error tracebacks.
* Tweak bison build rules so that we get the same error messages fromTom Lane2003-01-31
| | | | | | | | bison 1.875 and later as we did from earlier bison releases. Eventually we will probably want to adopt the newer message spelling ... but not yet. Per recent discussion on pgpatches. Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql grammars, since these do not affect regression test results.
* Allow a time zone to be specified (and silently ignored) in the inputTom Lane2003-01-31
| | | | | | | for type 'time without time zone', as we already did for type 'timestamp without time zone'. This patch was proposed by Tom Lockhart on 7-Nov-02, but he never got around to applying it. Adjust regression tests and documentation to match.
* Handle mixed-case names properly in plpgsql_parse_tripwordtype.Tom Lane2003-01-31
| | | | From Neil Conway.
* Fix regression in .pgpass support. From Neil Conway.Tom Lane2003-01-30

* SPI_exec shouldn't return SPI_OK_SELECT if it hasn't actually returnedTom Lane2003-01-29
| | | | | a tuple table. Fixes core dump in pltcl (and probably other PLs) when executing a query rewritten by a rule. Per bug report from Wolfgang Walter.
* Update release steps.Bruce Momjian2003-01-29
|
* Tweak ArrayCount() to forestall possible access to temp[-1]. ProblemTom Lane2003-01-29
| | | | | | cannot actually happen at present because ArrayCount() is only called on strings beginning with '{', but seems best to prevent it going forward. Per report from Yichen Xie.
* Guard against array overrun, per report from Yichen Xie. This caseTom Lane2003-01-29
| | | | | can only occur if the constant DEFAULT_CLIENT_AUTHSVC is given a bogus value, so it doesn't seem worth back-patching, but I'll fix it in HEAD.
* Repair array subscript overrun identified by Yichen Xie. Reduce theTom Lane2003-01-29
| | | | | | | value of MAX_TIME_PRECISION in floating-point-timestamp-storage case from 13 to 10, which is as much as time_out is actually willing to print. (The alternative of increasing the number of digits we are willing to print looks risky; we might find ourselves printing roundoff garbage.)
* Fix array subscript overruns identified by Yichen Xie.Tom Lane2003-01-29
|
* Extend join-selectivity API (oprjoin interface) so that join type isTom Lane2003-01-28
| | | | | | | passed to join selectivity estimators. Make use of this in eqjoinsel to derive non-bogus selectivity for IN clauses. Further tweaking of cost estimation for IN. initdb forced because of pg_proc.h changes.
* Convert variable name to canonical spelling before checking for matchesTom Lane2003-01-28
| | | | | in GUCArrayAdd/GUCArrayDelete. This prevents the multiple-entry bug exhibited by Frank Lupo 28-Jan-2003.
* Revert off setting mention for client_min_messages.Bruce Momjian2003-01-28
| | | | | Set log_min_error_messages to the proper and agreed-upon default, PANIC (off). (BACKPATCH)
* Revert optimizer page count change.Bruce Momjian2003-01-28
|
* Set log_min_error_messages to the proper and agreed-upon default, PANIC (off).Bruce Momjian2003-01-27
| | | | Backpatch to 7.3.X.
