I've done this (collecting the data), and actually what I have is BOTH,
last vacuum and last
autovacuum, as well as last analyze and last autovacuum analyze.

Do folks want both, or is just one sufficient.

I posted a WIP patch yesterday that just does the collection and
storage, but not
added the columns to the views.

I'm planning on doing the view stuff and docs today.

Comments/feedback welcome.
