yeah -- I've seen a bit of interest in this feature, but AFAIK nobody's working on it, and no plausible design has been submitted (which is a giant red flag in terms of 9.2 acceptance). fair warning: this is one of those items that sounds neat but is a lot more complicated than it looks. in the meantime, just do the workaround I do: make an immutable function that takes your type as input, and manually apply the constraint in various places like (like as a table constraint). merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
