list, when some of the child rels have been excluded by constraint exclusion. This doesn't save a huge amount of time but it'll save some, and it makes the EXPLAIN output look saner. We already did the equivalent thing in set_append_rel_pathlist(), but not here.

contradictory WHERE-clauses applied to a relation. This makes the GUC variable constraint_exclusion rather inappropriately named, but I've refrained for the moment from renaming it. Per example from Martin Lesser.

This doesn't matter too much for ordinary NOTs, since prepqual.c does its best to get rid of those, but it helps with IS NOT TRUE clauses which the rule rewriter likes to insert. Per example from Martin Lesser.

that's shorter-lived than the expression state being evaluated in it really doesn't work :-( --- we end up with fn_extra caches getting deleted while still in use. Rather than abandon the notion of caching expression state across domain_in calls altogether, I chose to make domain_in a bit cozier with ExprContext. All we really need for evaluating variable-free expressions is an ExprContext, not an EState, so I invented the notion of a "standalone" ExprContext. domain_in can prevent resource leakages by doing a ReScanExprContext on this rather than having to free it entirely; so we can make the ExprContext have the same lifespan (and particularly the same per_query memory context) as the expression state structs.

the DROP pass rather than the ADD_CONSTR pass. On examining the code I think this was just an oversight rather than intentional, and it seems to satisfy the principle of least surprise better than the alternative solution that was discussed. Add an example to the ref page showing how to do ALTER TYPE and update the default in one command. Per gripe from Markus Bertheau that that wasn't possible.

check). This isn't supported by pg_regress since the recent rewrite into C. While we could add char classes to pg_regress.c's code, it's not really needed at the moment: thanks to Andrew's patch to make pg_regress always accept the 'standard' comparison file, we can just drop the version check.
