The patch picked up a whole other set of changes as well.

How about:

n_distinct_inherited exists to allow the distinct value estimate to be
overwritten for the children-included statistics gathered for inheritance
parent tables, and for partitioned tables.

I can live with “ordinarily” with that wording, it is just the negative of
“children-included”.
