I alluded to this in [0], but it's better discussed in its own thread.
I think the check that makes pgstattuple_approx reject TOAST tables is a
mistake. They have visibility and free space map, and it works just
fine if the check is removed.
Attached is a patch to fix this and add some tests related to how
pgstattuple and pg_visibility accept TOAST tables for inspection.

I gave the patch a spin, and it passes regression tests and didn't
cause any problems when I played with it.
No upgrade or dump considerations, of course.
This is a clear improvement.
I'll mark the patch as "ready for committer".
committed, thanks
