Thanks for the proposal and the patch.
You said this patch was a first draft version, so these may be too minor
comments, but I will share them:

Should we also note this is the default, i.e. not using ONLY option
behavior here?

This part also should be modified, shouldn't it?
When running ANALYZE VERBOSE ONLY on a partition table, the INFO message
is like this:
=# ANALYZE VERBOSE ONLY only_parted;
INFO: analyzing "public.only_parted" inheritance tree
I may be wrong, but 'inheritance tree' makes me feel it includes child
tables.
Removing 'inheritance tree' and just describing the table name as below
might be better:
INFO: analyzing "public.only_parted"
