* Revise aggregate functions per earlier discussions in pghackers.Tom Lane2000-07-171-1/+4
| | | | | | | | | | | 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...
* First stage of reclaiming memory in executor by resetting short-termTom Lane2000-07-121-32/+29

* Fix handling of NULL constraint conditions: per SQL92 spec, a NULL resultTom Lane2000-01-191-4/+2
| | | | | | | | | 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.
