I like the idea of being able to define more flexible foreign keys, but are we gilding the lily here? The proposed solution is really quite specific to the nuances of arrays. Perhaps there is a more general expression based syntax that leaves the door open for other types conditions such as dealing fields dependent on other fields? merlin -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
