Implementation of ctime, mtime, atime will have little bit higher impact than just creation time - and these values should be moved to statistics instead bloated pg_class. You cannot use a filesystem data, because some requests are solved by cache not by filesystem. I had to emulate MySQL fields - and this was a first implementation, but totally useles - now we have a solution based on enhancing pg_stat and it works as expected Regards Pavel > > ---------------- > Hannu > > > > > -- > Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-hackers -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
