Uh, yes. I am sorry. I thought the user wanted a field that could only
be accessed via a password. I suppose it could be built using the
pgcrypto routines, but I question how secure it would be because the
password would have to pass over the network in plantext as part of the
query. You could do something similar to what we do with wire
encryption now by encrypting on the client side with a random salt
supplied by the server and comparing that, but that doesn't sound
secure.
I think your best bet is to do encryption/decryption on the client side
and store only the encrypted part in the database.
