Dave Cramer	985e551b48	Applied Kris Jurkas patch to fix rollback and SQLException	23 years ago
Dave Cramer	d23fd9572b	applied patch from Oliver Jowett	23 years ago
Barry Lind	28ce9f0fed	Two patches from Kris Jurka. One fixes a problem with incorrect type for double 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	23 years ago
Barry Lind	16a30346c8	Patch from Nic Ferrier to add support for result sets being cursor based so that rows can be fetched incrementally. This is enabled by using setFetchSize()	23 years ago
Tom Lane	2d1f940542	Minor code cleanup: remove no-longer-useful pull_subplans() function, and convert pull_agg_clause() into count_agg_clause(), which is a more efficient way of doing what it's really being used for.	23 years ago
Tom Lane	85caf1784a	Detect duplicate aggregate calls and evaluate only one copy. This speeds up some useful real-world cases like SELECT x, COUNT() FROM t GROUP BY x HAVING COUNT() > 100.	23 years ago
Tom Lane	ef5842b5f7	#ifdef out stuff that shouldn't be compiled when not USE_SSL. Curious that gcc doesn't complain about unreferenced static variables.	23 years ago
Tom Lane	3752e85bad	Determine the set of constraints applied to a domain at executor 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.	23 years ago
Bruce Momjian	464598b637	Add mention of CURRENT_SCHEMA for object creation.	23 years ago
Bruce Momjian	6b196c0754	Don't print NO ACTION foreign key actions in dumps and psql \d.	23 years ago
Tom Lane	4cff59d8d5	Tweak planner and executor to avoid doing ExecProject() in table scan 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%.	23 years ago
Bruce Momjian	0d3e36b668	Move pg_service.conf.sample to /interfaces/libpq.	23 years ago
Bruce Momjian	802a4d4111	Change MOVE LAST to MOVE ALL. Standard says FETCH LAST is after last row, and we don't do that.	23 years ago
Tom Lane	c7bceca156	Implement EXPLAIN EXECUTE. By Neil Conway, with some kibitzing from Tom Lane.	23 years ago
Tom Lane	6adb475f77	Update release history for 7.3.2.	23 years ago
Tom Lane	967e8a37ab	Fix nodeUnique to behave correctly when reversing direction after reaching either end of subplan results. This prevents misbehavior of cursors on SELECT DISTINCT ... queries. Per bug report 1-Feb-02.	23 years ago
Tom Lane	6ba8af9d5d	Remove restriction that cast functions cannot be volatile. This 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.	23 years ago
Tom Lane	e0a1ee2053	Cleaner solution to the problem of loading pre-7.3 dumps containing 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.	23 years ago
Tom Lane	330b4e4215	Changes of 6-Sep-02 broke pg_restore's ability to recognize tar-format files. Fix it.	23 years ago
Tom Lane	21166170c8	Fix assign_session_authorization() to not be confused by all-numeric user names. Per recent reports.	23 years ago
Tom Lane	361eaa185f	Prevent core dump from calling Tcl_DontCallWhenDeleted() with a null interp pointer. Per report from Gerhard Hintermayer.	23 years ago
Tom Lane	032235cafe	Apply ljb's patch to prevent both memory leak and core dump during 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.	23 years ago
Tom Lane	f51c7ca182	Make plpython's spi_execute interface handle NULLs properly. From Andrew Bosma.	23 years ago
Tom Lane	6f49703f0e	Clean up plpython error reporting so that its regression test passes with some amount of cleanliness. I see no need to report the internal Python name rather than the SQL procedure name in error tracebacks.	23 years ago
Tom Lane	9d00798720	Tweak bison build rules so that we get the same error messages from 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.	23 years ago
Tom Lane	bd96dd1184	Allow a time zone to be specified (and silently ignored) in the input 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.	23 years ago
Tom Lane	37b247a5e9	Handle mixed-case names properly in plpgsql_parse_tripwordtype. From Neil Conway.	23 years ago
Tom Lane	0de771dd5c	Fix typo, per Neil Conway.	23 years ago
Tom Lane	4ec457ad58	Fix regression in .pgpass support. From Neil Conway.	23 years ago
Tom Lane	887edf4ff7	Update release history for 7.2.4.	23 years ago
Tom Lane	26f56131ae	SPI_exec shouldn't return SPI_OK_SELECT if it hasn't actually returned 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.	23 years ago
Bruce Momjian	6976205b4b	Update release steps.	23 years ago
Tom Lane	5fdb142f16	Tweak ArrayCount() to forestall possible access to temp[-1]. Problem 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.	23 years ago
Tom Lane	3cb282f3e6	Guard against array overrun, per report from Yichen Xie. This case 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.	23 years ago
Tom Lane	23b8a0ce61	Repair array subscript overrun identified by Yichen Xie. Reduce the 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.)	23 years ago
Tom Lane	b8add56ed0	Fix array subscript overruns identified by Yichen Xie.	23 years ago
Tom Lane	2e46b762eb	Extend join-selectivity API (oprjoin interface) so that join type is 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.	23 years ago
Peter Eisentraut	955a1f81a7	Factor out the code that detects the long long int snprintf format into a separate macro. Also add support for %I64d which is the way on Windows. The code that checks for the 64-bit int type now gives more reasonable results when cross-compiling: In that case we just take the compiler's information and trust that the arithmetic works. Disabling int64 is too pessimistic.	23 years ago
Tom Lane	c0276244b1	Convert variable name to canonical spelling before checking for matches in GUCArrayAdd/GUCArrayDelete. This prevents the multiple-entry bug exhibited by Frank Lupo 28-Jan-2003.	23 years ago
Bruce Momjian	7af352d091	Revert off setting mention for client_min_messages. Set log_min_error_messages to the proper and agreed-upon default, PANIC (off). (BACKPATCH)	23 years ago
Bruce Momjian	f21fb30dfc	Revert optimizer page count change.	23 years ago
Bruce Momjian	bd175cc9fb	Set log_min_error_messages to the proper and agreed-upon default, PANIC (off). Backpatch to 7.3.X.	23 years ago
Bruce Momjian	d42a476621	Add blank line.	23 years ago
Bruce Momjian	c177ba99bd	Move: > * Add the concept of dataspaces/tablespaces [tablespaces] 307d307 < * Add the concept of dataspaces/tablespaces [tablespaces]	23 years ago
Bruce Momjian	9b9b14915b	Fix typo 233 pages -> 333 pages.	23 years ago
Tom Lane	70fba70430	Upgrade cost estimation for joins, per discussion with Bradley Baetz. Try to model the effect of rescanning input tuples in mergejoins; account for JOIN_IN short-circuiting where appropriate. Also, recognize that mergejoin and hashjoin clauses may now be more than single operator calls, so we have to charge appropriate execution costs.	23 years ago
Bruce Momjian	b2773d4099	Remove mention of 6.5 max backends.	23 years ago
Tom Lane	33875872fd	Get rid of last few unadorned 'permission denied' messages.	23 years ago
Tom Lane	4b833d080b	Prevent core dump when die_horribly() is called with null AH pointer. Problem reported and fixed by Oliver Elphick.	23 years ago
