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. -- output = reverse("ofni.sesabatadxunil" "@" "enworbbc") http://www3.sympatico.ca/cbbrowne/postgresql.html Rules of the Evil Overlord #181.
