It's not an operator (in the sense of something with a pg_operator OID), which means this would be quite a bit less than trivial as far as internal representation/implementation goes. I'm not sure if there would be grammar issues, either. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
