No, he has to actually SET ROLE to the superuser account to make himself a superuser. SUPERUSER and the other non-GRANTable attributes of a role don't inherit through mere membership. This is partly an implementation limitation but I happen to think it's a good idea ... superuserness is a mighty big hammer to be letting loose accidentally. regards, tom lane
