Actually, given that you are nearly full on that disk, you probably
need more disk.  You ought to be able to trim some things out of
/var/log.  But you can't delete anything from the PostgreSQL area
(/var/lib/pgsql/*, it looks like).  There's no "clean up" you can do
there -- your data is there.

You _may_ need a vacuum full -- if you have a lot of dead tuples, you
might be able to recover some disk space.  It'll lock all the tables,
so you'll need to be able to take an outage to do this.  In the psql
command monitor (psql -U postgres [yourdbname]) you can issue a
VACUUM FULL VERBOSE and recover available space (and find out how
much you're recovering -- that's what the VERBOSE does).  Note that
this may take a _long_ time to complete (depending how big oyur
database is), and (as I noted) it will cause your application not to
work while it's going on.
