Tom Lane 82d8ab6fc4 Fix the plan-invalidation mechanism to treat regclass constants that refer to ... a relation as a reason to invalidate a plan when the relation changes. This handles scenarios such as dropping/recreating a sequence that is referenced by nextval('seq') in a cached plan. Rather than teach plancache.c all about digging through plan trees to find regclass Consts, we charge the planner's setrefs.c with making a list of the relation OIDs on which each plan depends. That way the list can be built cheaply during a plan tree traversal that has to happen anyway. Per bug #3662 and subsequent discussion.		2007-10-11 18:05:27 +00:00
