If ubuntu or debian  /var/cache/apt/archives/* can safely be removed
and will often free up a lot of space, (or on redhat
/var/cache/yum/*/packages/*)

If you installed from source you may have several daily log files you
can remove, redhat seems also to keep the logs around
thse files are often found in /var/lib/pgsql/data/pg_log and should
contain ascii text. Debian and ubuntu put them in /var/log/postgres
and use logrotate to trim them, but there maybe other files in /var/log
that can be truncated or erased to free up space.
