I haven't looked closely at this version but I did notice that you do
not document that parallel vacuum disables eager scanning. Imagine you
are a user who has set the eager freeze related table storage option
(vacuum_max_eager_freeze_failure_rate) and you schedule a regular
parallel vacuum. Now that table storage option does nothing.
