Sure, except that it will also call your function when someone does my_int + text or my_int + bytea or my_int + box, which are surely a lot less sensible. It's probably a good idea to assume that if you make your type work like the existing types, it's more likely to end well than if you make it behave completely differently. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
