Probably fixed here:

2005-03-31 18:20  tgl

	* src/backend/postmaster/: pgstat.c (REL7_4_STABLE), pgstat.c
	(REL8_0_STABLE), pgstat.c: Flush any remaining statistics counts
	out to the collector at process exit.  Without this, operations
	triggered during backend exit (such as temp table deletions) won't
	be counted ... which given heavy usage of temp tables can lead to
	pg_autovacuum falling way behind on the need to vacuum pg_class and
	pg_attribute.  Per reports from Steve Crawford and others.
