Most of the other behaviors you mention are also partly or wholly dependent on which software you use with Postgres and whether you've correctly configured that software. So it's pretty hard to answer this usefully with only this much info. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
