what should i put in /etc/pam.d/postgresql ? i dont know how works pam, i'll read about it, but not enough time for now, i added theses lines to /etc/pam.d/postgresql file: auth required pam_unix.so nullok_secure account required pam_unix.so it works, auth via my unix users, is it the best way, the safest way? thanks for help Bruno ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
