I knew that would come up eventually :D. Believe me, I'd love to dig
in, but I haven't had a postgres dev tree on my system in years and I
don't have any time for it right now. (But there's always time to
banter in the mailing list, right? :-) )

Actually what I meant was that autovacuum will always just vacuum. In
some cases I'd rather it cluster instead. But on that note, it would
also be madly useful to give CLUSTER the ability to ANALYZE as well.
