You and Nathan appear to like it, and no one else has objected.
I shall make it so.

Philip: the rule that pg_dump needs to apply w.r.t. defaults for
inherited fields is that if an inherited field has a default and
either (a) no parent table supplies a default, or (b) any parent
table supplies a default different from the child's, then pg_dump
had better emit the child field explicitly.
