Uh ... why? The cooked tree should be stored in pg_constraint, no?
What's the point of redoing the parse analysis phase?
BTW, this should be a lot easier to do cleanly (ie, without memory
leaks) now that there's a notion of expression state trees. You can
attach the information loaded from pg_constraint to the expression state
node for the CoerceToDomain node (being careful to copy it into
estate->es_query_cxt). Maybe that was already apparent to you ...
