Author	SHA1	Message	Date
Tom Lane	da5f1dd722	Revise union_planner and associated routines to clean up breakage ... from EXCEPT/HAVING patch. Cases involving nontrivial GROUP BY expressions now work again. Also, the code is at least somewhat better documented...	27 years ago
Tom Lane	605d84941d	Clean up cost_sort some more: most callers were double-counting ... the cost of reading the source data.	27 years ago
Tom Lane	17dbeebb5f	Fill in reasonable-looking cost estimates in inserted nodes. ... This makes no difference to the optimizer, which has already decided what it's gonna do, but it makes the output of EXPLAIN much more plausible.	27 years ago
Tom Lane	7a7ba33536	Clean up some bogosities in path cost estimation, like ... sometimes estimating an index scan of a table to be cheaper than a sequential scan of the same tuples...	27 years ago
Tom Lane	11a0027e28	Fix nasty little typo that prevented get_cheapest_path_for_joinkeys ... from ever returning a path. This put a bit of a crimp in the system's ability to generate intelligent merge-join plans...	27 years ago
Tom Lane	970583ab4f	Several routines in setrefs.c would crash on array refs ... due to lack of check for recursing into a null subexpression.	27 years ago
Tom Lane	eb00bdf237	Insert a test for missing targetlist entry in replace_agg_clause.	27 years ago
Tom Lane	4438b70b94	Repair some problems in planner's handling of HAVING clauses. ... This fixes a few of the problems Hiroshi Inoue complained of, but I have not touched the rewrite-related issues.	27 years ago
Tom Lane	e91f43a122	Fix potential overflow problems when relation size exceeds ... 2gig. Fix failure to reliably put the smaller relation on the inside of a hashjoin.	27 years ago
Tom Lane	ff38837fe9	Fix nasty bug in optimization of multiway joins: optimizer ... would sometimes generate a plan that omitted a sort step before merge.	27 years ago
Bruce Momjian	bd6f98af31	I suggest the following portability patch, which does not ... change functionality, but makes the code more ANSI C'ish. My AIX xlc compiler barfs on all of these. Can someone please review and apply to current. <<port.patch>> Thanks Andreas	27 years ago

Bruce Momjian	f7430af934	Fix OR index selectivity problem.	27 years ago
Bruce Momjian	c831d08fac	Fix for Alpha OR selectivity bug.	27 years ago
Tom Lane	e0345e09bf	Partial fix for copied-plan bugs reported by Hiroshi Inoue: ... _copyResult didn't copy subPlan structure completely. _copyAgg is still busted, apparently because of changes from EXCEPT/INTERSECT patch (get_agg_tlist_references is no longer sufficient to find all aggregates). No time to look at that tonight, however.	27 years ago
Tom Lane	b204d10c79	Executor no longer cares about mergejoinop, mergerightorder, mergeleftorder, ... so remove them from MergeJoin node. Hack together a partial solution for commuted mergejoin operators --- yesterday a mergejoin int4 = int8 would crash if the planner decided to commute it, today it works. The planner's representation of mergejoins really needs a rewrite though. Also, further testing of mergejoin ops in opr_sanity regress test.	27 years ago
