Tom Lane ea166f1146 Planner speedup hacking. Avoid saving useless pathkeys, so that path ... comparison does not consider paths different when they differ only in uninteresting aspects of sort order. (We had a special case of this consideration for indexscans already, but generalize it to apply to ordered join paths too.) Be stricter about what is a canonical pathkey to allow faster pathkey comparison. Cache canonical pathkeys and dispersion stats for left and right sides of a RestrictInfo's clause, to avoid repeated computation. Total speedup will depend on number of tables in a query, but I see about 4x speedup of planning phase for a sample seven-table query.		2000-12-14 22:30:45 +00:00
