That's true.  My preference would be to have an unencrypted connection via UNIX socket from the application to haproxy, then an encrypted connection using SSL certificate authentication from haproxy to the database.  I spent some time attempting this.  But that doesn't seem to be possible since haproxy doesn't understand the postgres protocol.
