The only reason that it would be necessary for VACUUM to "take the
site down" would be if you are running version 7.1, which was
obsoleted in 2002, which, it should be noted, was SIX YEARS AGO.
As has been noted, you seem to be presupposing a remarkably complex
solution to resolve a problem which is likely to be better handled via
running VACUUM rather more frequently.
