Somebody who has the ability to rewrite pg_hba.conf could also go in and physically alter the database files -- those are in the same directory tree, with the same ownership and permissions, as pg_hba.conf. If you cannot trust people who have that level of access, you have a problem that software cannot solve for you. You need to rethink who has got access to the machine running the database server, or at least who has got root on it. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
