Tom Lane 5a7471c307 Add COST and ROWS options to CREATE/ALTER FUNCTION, plus underlying pg_proc ... columns procost and prorows, to allow simple user adjustment of the estimated cost of a function call, as well as control of the estimated number of rows returned by a set-returning function. We might eventually wish to extend this to allow function-specific estimation routines, but there seems to be consensus that we should try a simple constant estimate first. In particular this provides a relatively simple way to control the order in which different WHERE clauses are applied in a plan node, which is a Good Thing in view of the fact that the recent EquivalenceClass planner rewrite made that much less predictable than before.		2007-01-22 01:35:23 +00:00
