You're obviously suffering serious table bloat :-(. Depending on how
heavy the update traffic on that table is, it might be that once-a-day
vacuum is simply not often enough. Another likely problem is that you
need to increase the FSM settings (how big is your whole database?)

VACUUM FULL will fix the immediate problem. You might well find CLUSTER
to be a faster alternative, though.
