I'm not sure why this is suggested as being part of pg_freespace and
not part of pageinspect? (Which is where all the other inspection
tools live).

If I wanted to see the vismap (and I do...) then I'd like to see the
whole vismap, not just the part that relates to blocks currently in

If you do want that, you can just join the two things together
(function to see vismap joined to pg_freespace).

(Having said that, I don't have a major objection to it being in
pg_freespace as well).
