How to store passwords in PostgreSQL with pgcrypto?

Can a pgcrypto application send a crypto key?
If you use pgcrypto’s in-database crypto functions you can have the application send the key along with the data, which is at least somewhat helpful.
What’s the best way to decrypt a database?
The best way is to do the crypto on the client or application server, so the database has no idea what the keys are and cannot decrypt the data. If the client / appserver are on a different host, all the better. If your database is encrypting and decrypting the data for you, then it’s vulnerable to having the keys stolen along with the database.

The naive and direct way seems to be to store the private key and password using Heroku’s ENV variables. However this seems like it doesn’t add much security since both values are now easily accessed by anyone with access to the environment.
