Some people say that VACUUM nukes their performance, and some don't
find it to be a problem. AFAICT, it's only an issue if you have little
reserve disk bandwidth, which in itself is a dangerous situation for a
database that you don't want to pay attention to.
I don't want to sound like I'm rejecting your patch out of hand. What
I do want is to get some idea of its range of usefulness.

"Unattended" and "running on the edge of your resources" don't play nice
together, for sure.
