Well, I am worried about this change idea. That's potentially going to
break applications, ALTER ... DROP CONSTRAINT and SET CONSTRAINTS both use
the constraint names. I think maybe something like adddepend in contrib
was for 7.2 or 7.3 might be better since that makes it something that's
not automatically done but relatively easily done.
