Which is why you might be better off putting the new field at the end of the table and using an administrative view to make your viewing easier. I can't really think of any real reason to put the field at a particular position, applications don't reallty care about the order of fields. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
