It seems very unlikely that this "just happened" without somebody/something outside Postgres actively breaking it. I'd take a close look at recent system configuration changes, particularly in the firewall area. It wouldn't hurt to know exactly *why* the system was rebooted, too. 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
