problem with upgrade from 6.5 -> 7.2

this set of permissions exists under 6.5
bzsdb02=> \z
Database    = bzsdb02
 +------------------------+----------------------------------------+
 | Relation               | Grant/Revoke Permissions               |
 +------------------------+----------------------------------------+
 | name_server            | {"=","namereader=r","nameadmin=arwR"}  |
 | name_server_serial_seq |                                        |
 | nsconfig               | {"=","namereader=r","nameadmin=arwR"}  |
 | nsnotify               | {"=","namereader=rw","nameadmin=arwR"} |
 +------------------------+----------------------------------------+

and under 7.2

bzsdb02=# \z
                    Access privileges for database "bzsdb02"
         Table          |                   Access privileges
------------------------+-------------------------------------------------------
name_server | {=,postgres=arwdRxt,namereader=r,nameadmin=arwdRxt}
name_server_serial_seq |
nsconfig    | {=,postgres=arwdRxt,namereader=r,nameadmin=arwdRxt}
nsnotify    | {=,postgres=arwdRxt,namereader=rwd,nameadmin=arwdRxt}
(4 rows)

note that "name_server_serial_seq" appear to be identical

However, when I attempt to update the database in 7.2 I get this error:

DBD::Pg::st execute failed: ERROR:  name_server_serial_seq.nextval: you
don't have permissions to set sequence name_server_serial_seq

Any ideas?
I suppose I could add the permissions but it seems they should follow
along from the CREATE sequence statement ???

Thanks,

Michael

The dump looks like this

CREATE SEQUENCE "name_server_serial_seq" start 5202 increment 1 maxvalue
2147483647 minvalue 1  cache 1 ;
SELECT nextval ('"name_server_serial_seq"');

CREATE TABLE "name_server" (
... blah, blah....
        "serial" int8 DEFAULT nextval ( 'Name_Server_Serial_Seq' ));
REVOKE ALL on "name_server" from PUBLIC;
GRANT SELECT on "name_server" to "namereader";
GRANT ALL on "name_server" to "nameadmin";

... table gets loaded....

CREATE UNIQUE INDEX "name_server_key" on "name_server" using btree (
"serial" "int8_ops" );
