Autovac is also going to promote itself to uninterruptible once every 150e6
transactions (by the default settings).

To stop using manual vacuums is not going to be a complete cure anyway.

It would be nice to know why the scripts are doing the manual vacuum.  Just
out of mythology, or is there an identifiable reason?
