I'd actually highly recommend the autovacuum daemon with moderately
aggressive settings, i.e. have it come on and check every 5 or 10 minutes.
On a table that's being updated many times a second, the needs for
vacuuming can be very frequent.  let the autovacuum daemon do it.  You can
schedule in mandatory plain vacuum s every couple of hours to make sure
they happen if you're paranoide, but honestly, while the autovacuum daemon
may technically be beta, it seems to be working for an awful lot of
people with heavily updated sites.
