I recall we had some discussion on changes to group locking for
implementing parallel heap vacuum, but I don't remember if we have a
blocker now.
One problem we previously had was that since the relation extension
locks were not in conflict between parallel workers and the leader,
multiple workers could extend the visibility map simultaneously. This
problem was fixed by commit 85f6b49c2c.
