Maybe you need to rethink who owns which tables in your design. (Yes, you could use event triggers to interfere with the normal system behavior, but that doesn't make it a good idea.) The owner can revoke her own TRUNCATE privilege, but that's just a mistake preventer, since she can also re-grant the privilege to herself. regards, tom lane
