Try updating to PG 8.1 ...

* src/backend/postmaster/pgstat.c: Make backends that are reading
the pgstats file verify each backend PID against the PGPROC array.
Anything in the file that isn't in PGPROC gets rejected as being a
stale entry. This should solve complaints about stale entries in
pg_stat_activity after a BETERM message has been dropped due to
overload.
