Having log_hostname off is supposed to prevent us from attempting a reverse DNS lookup ... but it would be worth checking into whether one is happening anyway. (I would think though that such activity would be visible in strace/truss output. Perhaps you should turn log_hostname *on* and verify that you see the lookup activity in strace that wasn't there before.) 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
