Re: [BUGS] Can postgres run autovacuum tasks when autovacuum is disabled?

Nope, scratch that: I missed the bit before the launcher's main loop,
where it fires off one child and exits if it's launched when autovacuum
is already false.

Still, if it does fire one child process, it looks like that child will
vacuum everything that seems to need vacuuming in the target database.
We should probably adjust that so that tables not in danger of wraparound
get skipped.
