You want a normalized table anyhow.  If you want something
denormalized, use a view.

This is better as:

CREATE TABLE phone (
    cod VARCHAR,
    num VARCHAR,
    PRIMARY KEY(cod, num)
);

CREATE TABLE person (
    name varchar,
    PRIMARY KEY(name)
)

CREATE TABLE person_phone (
    name VARCHAR NOT NULL REFERENCES person(name),
    cod VARCHAR,
    num VARCHAR,
    FOREIGN KEY(cod, num) REFERENCES phone(cod, num),
    PRIMARY KEY(name, cod, num)
);

Cheers,
David.
