First off you shouldn't need to restart PG.  When it wasn't working did
you ever check the autovacuum_enabled setting? For example within psql:
"show autovacuum;".

I would venture to guess that autovacuum was disabled for some reason.
Perhaps last time you started the server the stats settings weren't enabled?
