I found this with Google, maybe it will help you.

CREATE TABLE crypto (
id SERIAL PRIMARY KEY,
title VARCHAR(50),
crypted_content BYTEA
);


INSERT INTO crypto VALUES (1,'test1',encrypt('daniel', 'fooz', 'aes'));
INSERT INTO crypto VALUES (2,'test2',encrypt('struck', 'fooz', 'aes'));
INSERT INTO crypto VALUES (3,'test3',encrypt('konz', 'fooz', 'aes'));

SELECT * FROM crypto;

SELECT *,decrypt(crypted_content, 'fooz', 'aes') FROM crypto;

SELECT *,decrypt(crypted_content, 'fooz', 'aes') FROM crypto WHERE
decrypt(crypted_content, 'fooz', 'aes') = 'struck';

I could not test it, since I do not have pgcrypto installed.
