Hi Konstantin,

Is there any reason why you don't want to split this into two separate
proposals?  One for remove_restrictions_implied_by_constraints() and
one for the operator_predicate_proof() changes.

Your v3 patch breaks the new partition_join test (the recently
committed partition-wise join stuff), as far as I can tell in a good
way.  Can you please double check those changes and post an updated
patch?
