Maybe the original message is about SSH proxy instead of tunneling?
The PostgreSQL protocol makes a SSH upgrade instead of starting the
communication with SSH handshake and that is a problem when using some
SSH proxies/load balancers which are nowadays common in cloud
environments. I also wish there was a way to connect directly to a SSH
socket but that is not about the driver but how PostgreSQL communication
protocol I guess.
