I don't think I understand the design you have in mind. I'm actually not clear that it would be all that bad to assume fixed operator names, as we apparently do in a few places despite the existence of operator classes. But if that is bad, then I don't know how using @+ and @- instead helps anything. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
