Well, my problem with that is that I don't see TRUNCATE as being in the same camp as most other utility commands; thus I'm not sure there's really a coherent view for it and the rest. In the end it's just an optimized DELETE, and we didn't say that other DML needs to provide a view for utility commands either. - Andres -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
