Trigger and Trigger function.

Howdy y'all.

I have been trying to get a trigger and trigger function working. I have looked at the docs, copied the examples, and I
stillcannot get this to work. So, now I try you guys/gals. 

My test environment:
  Windows XP Pro (on my laptop)
  User account Postgre, with non-admin premissions
  PostgreSQL 8.0.3 (via msi)
  Installed the pl/pgsql language

I created a test database, named testdb. I created a schema called oc along with its own tablespace. The table creates
OK,but the function that is going to be called by the trigger gets a syntex error on the second line, where the
functionis named. 

My purpose is to get the last_touch field in the table to always have the timestamp when the record was inserted or
updated.

Thanks for the use of your expertise. Source code follows.

CREATE TABLE oc.optical
(
    id serial NOT NULL,
    created timestamp NOT NULL DEFAULT ('now'::text)::timestamp(6) with time zone,
    last_touch timestamp NOT NULL DEFAULT ('now'::text)::timestamp(6) with time zone,
    file varchar(30),
    CONSTRAINT optical_pk PRIMARY KEY (id) USING INDEX TABLESPACE oc
)
WITHOUT OIDS TABLESPACE oc;
ALTER TABLE oc.optical OWNER TO oc;

CREATE FUNCTION
oc.upd_last_touch()      <-- syntex error here
RETURNS TRIGGER AS
$upd_last_touch$
BEGIN
    IF TG_NAME = 'optical_trig' THEN
        UPDATE optical
        SET NEW.last_touch = current_timestamp
        WHERE NEW.id = id;
    END IF;
END;
$upd_last_touch$
LANGUAGE 'plpgsql' VOLATILE;

ALTER FUNCTION oc.optical_upd() OWNER TO oc;

CREATE TRIGGER optical_trig BEFORE UPDATE ON optical
FOR EACH ROW EXECUTE PROCEDURE upd_last_touch();
