Yeah. ISTM the whole point of TRUNCATE is "I don't care about serializability for this operation, give me efficiency instead". So I see nothing wrong with a (non-default) option for COPY that similarly trades away some semantic guarantees for efficiency's sake. There are an awful lot of bulk-load scenarios where people will gladly take that trade, and are not very interested in halfway points either. 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
