I also am leaning towards treating this as v19 material.  It's a nontrivial
behavior change, and this option is useful for major version upgrades,
which is an area that we really don't want to surprise users too much.
Furthermore, auto-analyze doesn't process partitioned tables, either, so
this introduces a bit of divergence.  (I'd love to see that project picked
up again someday.  Perhaps I will take a gander...)
