Alter table x add constraing

Hi,
I have a table that inherits most of it's columns. Is this the best,
or at least a good, way to add a constraint? Is there a more
convenient (less typing) way?

--sql snippet------
--
-- Name: pi_contact; Type: TABLE; Schema: admin; Owner: kellert;
Tablespace:
--

CREATE TABLE pi_contact (
department VARCHAR(64),
organization VARCHAR(64),
)
INHERITS (contact);

ALTER TABLE admin.pi_contact ADD PRIMARY KEY
(admin.pi_contact.contact_id);
--
-- Name: TABLE pi_contact; Type: COMMENT; Schema: admin; Owner: kellert
--

COMMENT ON TABLE pi_contact IS 'contains PI contact info, inherits
from admin.contact';

-- end ----------------------

thanks,
Tom
