I'd vote for only supporting the former. What worries me more about that syntax is the postfix-operator ambiguity --- I think it'll be hard to expand it to expressions. It might be better to put the operator at the front; or maybe you need an extra keyword in there. 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
