OTOH, the pg_inherits field that stores the OID of the child table does
not mention "child" in its name (inhrelid), although you are right that
inhpartitioned can be taken to mean that the inheritance parent
(inhparent) is partitioned.  In any case, system catalog documentation
which clearly states what's what might be the best guide for the confused.

Of course, we can add a comment in pg_inherits.h next to the field
explaining what it is for those reading the source code and confused about
what inhpartitioned means.
