Good call.

Hmm. Partitions *are* inheritance children, so we perhaps don't need the
part before the comma. Also, adding "automatically" somewhere in there
would be nice.
Or, one could just write: /* add an auto dependency for partitions */

I don't see why this patch should do it, if dependency.sql itself does
not? I mean dropping AUTO dependent objects is one of the contracts of
dependency.c, so perhaps it would make sense to query pg_class in
dependency.sql to check if AUTO dependencies work correctly.
