Hm, you are right. If one does decrypt the data on the database you have to sent the password to postgresql and so a administrator of the database could easily grasb the password.

So the only way to go, would be to perform en/decryption on the client side?

I wonder now; if somebody could achieve to get a snapshot of the database, they could also be able to get the log-file of postgresql.
So one would also have to make attention that the information like sql statements don't leak that way.
Are there other places where this kind of information could leak?
