If you only backed up that subdirectory, and not all of
/var/lib/pgsql/data, I'm afraid you're out of luck. You needed the
pg_log files too.

Routine pg_dump runs are recommended. You might care to consult the
discussion of backup procedures in the Administrator's Guide,
http://www.ca.postgresql.org/users-lounge/docs/7.1/postgres/backup.html
or the updated version in development docs,
