I think that's a complete nonstarter. Aside from the fact that such a
constraint will have no definable semantics, even the possibility that a
constraint doesn't mean what it appears to mean will prevent us from
making use of FK constraints for optimization --- something that's
pretty high on the planner to-do list.
