I should clarify: the version of the pg_dump bug that still exists in
HEAD is triggered by putting the child table in a different schema than
the parent. 7.3 has different behavior --- offhand I think that in 7.3
the problem can occur if the child table is created while search_path is
set differently than it was when the parent was created. (Of course,
across multiple pg_dump and reload cycles this may boil down to the same
thing. But there are more ways to burn yourself given the 7.3
implementation.)
