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?
