Tom Lane	5f7c2bdb53	sum() on int2 and int4 columns now uses an int8, not numeric, accumulator ... for speed reasons; its result type also changes to int8. avg() on these datatypes now accumulates the running sum in int8 for speed; but we still deliver the final result as numeric, so that fractional accuracy is preserved. count() now counts and returns in int8, not int4. I am a little nervous about this possibly breaking users' code, but there didn't seem to be a strong sentiment for avoiding the problem. If we get complaints during beta, we can change count back to int4 and add a "count8" aggregate. For that matter, users can do it for themselves with a simple CREATE AGGREGATE command; the int4inc function is still present, so no C hacking is needed. Also added max() and min() aggregates for OID that do proper unsigned comparison, instead of piggybacking on int4 aggregates. initdb forced.	25 years ago
Tom Lane	cb052e0bf1	Fix rule rewriter so that new ordering of ON INSERT actions applies ... in cases of qualified rules as well as unqualified ones. Tweak rules test to avoid cluttering output with dummy SELECT results. Update documentation to match code.	25 years ago
Tom Lane	5ce8ab96f5	Add regress test case for INSERT ... SELECT in rules.	25 years ago
Tom Lane	ed5003c584	First cut at full support for OUTER JOINs. There are still a few loose ... ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED!	26 years ago
Tom Lane	a95eec6792	Add a regress test case for SELECT count(*) FROM view, so that we'll ... know if that case ever breaks again...	26 years ago
Thomas G. Lockhart	d1e6368816	Clean up header for uniform appearance throughout tests.	26 years ago
Tom Lane	f851c6b07d	Add another ORDER BY to rules test; got tired of it 'failing' ... every time I tweak the optimizer...	27 years ago
Jan Wieck	fd1647706d	Fixed latest regression diff's by omitting viewowner in SELECT from pg_views. ... Jan	27 years ago
Jan Wieck	c8cc45b2f3	Fixed small bug in ruleutils and added output of pg_views and ... pg_rules to rules regression test. Jan	27 years ago
Tom Lane	dbce02f133	Add ORDER BY clauses to some select-from-view operations ... in rules regression test, in order to eliminate bogus test 'failures' that occur due to platform-dependent and join-implementation-dependent ordering of tuples. I'm not sure that I got all of the SELECTs that need ordering clauses --- we may need some more. But this takes care of the diffs between my platform and Jan's.	27 years ago
Thomas G. Lockhart	dfdb2e5fb0	Remove non-portable queries by replacing getpgusername() with a constant ... string.	27 years ago
Jan Wieck	be948af2e8	Added LIMIT/OFFSET functionality including new regression test for it. ... Removed CURRENT keyword for rule queries and changed rules regression accordingly. CURRENT has beed announced to disappear in v6.5. Jan	27 years ago
Jan Wieck	566c712c58	Revert some changes from the INTERSECT/EXPECT patch that broke ... rule system semantics by having Var nodes referenced across multiple parsetrees when rules split them. Added more tests to the rules regression test. The code in question resulted from v6.3 based development and was a little careless applied to the v6.5 source tree. Jan	27 years ago
Jan Wieck	28fc5d7b83	Reenabled parentheses for grouping multiple rule actions and ... added this syntax to rules regression test so it will show up if someone breaks it again. Jan	27 years ago
Tom Lane	1f27facc90	Add ORDER BY to ensure platform-independent results in rules test.	28 years ago
Bruce Momjian	f93b6974f9	Here's a combination of all the patches I'm currently waiting ... for against a just updated CVS tree. It contains Partial new rewrite system that handles subselects, view aggregate columns, insert into select from view, updates with set col = view-value and select rules restriction to view definition. Updates for rule/view backparsing utility functions to handle subselects correct. New system views pg_tables and pg_indexes (where you can see the complete index definition in the latter one). Enabling array references on query parameters. Bugfix for functional index. Little changes to system views pg_rules and pg_views. The rule system isn't a release-stopper any longer. But another stopper is that I don't know if the latest changes to PL/pgSQL (not already in CVS) made it compile on AIX. Still wait for some response from Dave. Jan	28 years ago
Thomas G. Lockhart	5a68fd56cd	Consolidate Jan's rules test into one file. ... Remove dependency on a specific Postgres user name in the results (Check result against CURRENT_USER with a boolean instead).	28 years ago
Marc G. Fournier	1a77894d46	Add rule tests to regression tests...	28 years ago
