Why is it restricted to that? You could do sasl negotiation as well from what I can see? And that'd theoretically also allow to negotiate whether the client supports different ways of doing auth? Not saying that that's easy, but I don't think it's a fundamental restriction. I also can imagine things like using selinux labeling of connections. We have several useful authentication technologies built ontop of plaintext exchange. Radius, Ldap, Pam afaics could be implemented as an extension? Greetings, Andres Freund
