Regular expression and array

I wont go into details about why im using this field as an array but
how would I select all the rows that have the first name 'Tom' out of
the 'names' field?

CREATE TABLE test (
id integer,
names character varying[]
);
INSERT INTO test VALUES (1, '{"''Josh Berkus''","''Peter
Eisentraut''","''Marc Fournier''"}');
INSERT INTO test VALUES (2, '{"''Tom Lane''","''Bruce
Momjian''","''Dave Page''"}');
INSERT INTO test VALUES (3, '{"''Jan Wieck''","''Oleg
Bartunov''","''Joe Conway''"}');
