dump order by

Hi all,
I would like to know if it is possible to dump a table ordered by its
primary key.
Take a look at the this test table...
\d test
                         Table "public.test"
 Column    |  Type   |     Modifiers
-----------+---------+---------------------------------------------------
 id        | integer | not null
 name      | text    |
 id_father | integer |
Indexes:
    "test_pkey" PRIMARY KEY, btree (id)
Foreign-key constraints:
    "test_id_father_fkey" FOREIGN KEY (id_father) REFERENCES test(id)

select * from test;
 id |      nome       | id_father
----+-----------------+-----------
  6 | Homer Simpson   |         5
  5 | Abraham Simpson |
 10 | Maggie Simpson  |         6
  1 | Ned Flanders    |
  2 | Maude Flanders  |
  9 | Bart Simpson    |         6
  3 | Rod Flanders    |         1
  4 | Todd Flanders   |         1
  7 | Marge Simpson   |
  8 | Lisa Simpson    |         6
(10 rows)

I would like to dump the table with this order:

COPY test (id, nome, id_father) FROM stdin;
1   Ned Flanders    \N
2   Maude Flanders  \N
3   Rod Flanders    1
4   Todd Flanders   1
5   Abraham Simpson \N
6   Homer Simpson   5
7   Marge Simpson   \N
8   Lisa Simpson    6
9   Bart Simpson    6
10  Maggie Simpson  6
\.

instead it is dumped like this:

COPY test (id, note, id_father) FROM stdin;
6   Homer Simpson   5
5   Abraham Simpson \N
10  Maggie Simpson  6
1   Ned Flanders    \N
2   Maude Flanders  \N
9   Bart Simpson    6
3   Rod Flanders    1
4   Todd Flanders   1
7   Marge Simpson   \N
8   Lisa Simpson    6
\.

and I can't upload the table because the foreing keys.
