Note, however, that if you have scheduled downtime and your db server
is fast enough, you can schedule a vacuum full / reindexdb during that
time.  We had a rogue query that made a few of our largest tables very
very bloated (like 95% bloat) and we had some downtime to fix it and
it was way easier to just do the whole db with vacuum full verbose,
then reindex.  I also had a chacne to set fill factors on some of the
tables that I'd wanted new fill factors on.
