Hi all.

A long time ago in 04b31609b63ce77fb9273193f07cf21b2a7176af ONLY keyword was added to all queries in src/backend/utils/adt/ri_triggers.c. Since that time foreign keys do not work with inheritance trees and it is mentioned in the documentation for all versions since at least 7.3.

I wonder what are the pitfalls of removing ONLY keyword from those queries? I have made such change, it passes all tests and foreign keys for partitioned tables do work, but I suppose that there are lots of places where it could break something.

Thanks in advance.
