Tom Lane	d3db2bd80c	Repair bug #2839: the various ExecReScan functions need to reset ... ps_TupFromTlist in plan nodes that make use of it. This was being done correctly in join nodes and Result nodes but not in any relation-scan nodes. Bug would lead to bogus results if a set-returning function appeared in the targetlist of a subquery that could be rescanned after partial execution, for example a subquery within EXISTS(). Bug has been around forever :-( ... surprising it wasn't reported before.	19 years ago

Tom Lane	782c16c6a1	SQL-language functions are now callable in ordinary fmgr contexts ... ... for example, an SQL function can be used in a functional index. (I make no promises about speed, but it'll work ;-).) Clean up and simplify handling of functions returning sets.	26 years ago
Tom Lane	bec98a31c5	Revise aggregate functions per earlier discussions in pghackers. ... There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...	26 years ago
Tom Lane	badce86a2c	First stage of reclaiming memory in executor by resetting short-term ... memory contexts. Currently, only leaks in expressions executed as quals or projections are handled. Clean up some old dead cruft in executor while at it --- unused fields in state nodes, that sort of thing.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Tom Lane	6d1efd76fb	Fix handling of NULL constraint conditions: per SQL92 spec, a NULL result ... from a constraint condition does not violate the constraint (cf. discussion on pghackers 12/9/99). Implemented by adding a parameter to ExecQual, specifying whether to return TRUE or FALSE when the qual result is really NULL in three-valued boolean logic. Currently, ExecRelCheck is the only caller that asks for TRUE, but if we find any other places that have the wrong response to NULL, it'll be easy to fix them.	26 years ago
