I was about to say that you can tune pg_autovacuum, but I just checked
your original post and you're running 8.0.x - not sure about that one.

You'll have to check the documentation for that version to see if you
can either:
1. exclude that table from pg_autovacuum
2. increase pg_autovacuum's sensitivity

If not, and this table is the most active, it might be simpler just to
run your own vacuum-ing from a cron job.
