third (but unlikely) possibility is there are various dropped tables,
etc which need to be deleted but there are stale postgresql processes
holding on to the fd.  This would only happen following a postmaster
crash or some other bizarre scenario, but i've seen it on production
box.  symptoms are du and df reporting different numbers.  solutions
is easy: reboot or stop postmaster and kill all postgresql processes
(or, if you are brave, do it with dbms running and nail all processes
not following postmaster, do a ps axf [on linux] to see them).
