Nope, that's not it. Still works fine here.
What do you get from
select conname, consrc from pg_catalog.pg_constraint
where contype = 'c' and conrelid = 'person'::regclass;
select conname, consrc from pg_catalog.pg_constraint
where contype = 'c' and conrelid = 'person_change_history'::regclass;
AFAICS from looking at the 7.3 pg_dump source, it should suppress any
constraint on person_change_history that looks identical to one of the
parent table's constraints in this query.
