I really don't understand why you're so hot to avoid changing the
default behavior of VACUUM. Name me even one user who *likes* the
current behavior (ie, VACUUM grabs exclusive lock)? IMHO the default
behavior *should* change. Otherwise you're just forcing people to
update their cron scripts, which they wouldn't need to touch if we
do it the way I want.
