Well, if you'll remind me of the last time we changed the OID of a
standard datatype, I'd put some credence in that argument.

Yeah, Bruce and I were talking about that, but on reflection I'm not
sure that there's much potential commonality. The thing that's most
problematic about ecpg is that it wants to offer client-side equivalents
of some server datatype-manipulation functions; and I don't actually see
much of any of that in the proposed patch. All that's really here is
format conversion stuff, so there's no hope of unifying that code
unless this patch adopts ecpg's choices of client-side representation
(which I believe are mostly Informix legacy choices, so I'm not sure we
want that).
