pg_dump not correctly saving schema with partitioned tables?

have database with many partitions.  each partition table has its own primary key sequence.
  Column  ||                          Modifiers                           
-----------++--------------------------------------------------------------uno_id    || not null default
nextval('cmp0004.cmt_uno_id_seq'::regclass)

when dumped and then resorted, the pk sequence is changed to an inherited- from table:

   Column    ||                      Modifiers                       
--------------++------------------------------------------------------uno_id       || not null default
nextval('uno_uno_id_seq'::regclass)

(another error is that the pk sequence does not spec the schema!)

is there any way I can reliably backup and restore the db?
