Isn't this reasonably well covered by Teodor's work to support
typmods for user-defined types? We've discussed how the typmod could
be effectively a key into a system catalog someplace, thus allowing it
to represent more than just an int32 worth of stuff. I'm not seeing
where your proposal accomplishes more than that can.
