Debian puts the PostgreSQL data in /var/lib/postgres and the PGDG RPMs
(the ones that PostgreSQL produces) puts the data in /var/lib/pgsql .
One other thing to think about.  If your machine has more than one
hard drive moving the pg_xlog directory to another spindle (and using
a symlink in your data directory) can really be helpful performance
wise, but you want to have plenty of room for the log files to grow.
