If transactions rollback, the serial value assigned during the rolled back transaction is skipped. This has been discussed many times, it's a tradeoff between losing some #s now and again and taking a huge performance and code complexity hit to avoid it. If you absolutely need consecutive #s, then serial is not for you and you should implement your own method of acquiring sequential numbers. -- Bill Moran http://www.potentialtech.com -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
