you forgot pgcrypto
http://www.postgresql.org/docs/9.0/static/pgcrypto.html
and I like their warning :


F.25.6.3. Security limitations

All pgcrypto functions run inside the database server. That means that all the data and passwords move between pgcrypto and client applications in clear text. Thus you must:

Connect locally or use SSL connections.

Trust both system and database administrator.

If you cannot, then better do crypto inside client application.
