I think, the way the abstractions are chosen in this patch, it is still
very much tied to how the libpq protocol works. For example, there is a
cancel key and a ready-for-query message. Some of the details of the
simple and the extended query are exposed. So you could create a
protocol that has a different way of encoding the payloads, as your
telnet example does, but I don't believe that you could implement a
competitor's protocol through this. Unless you have that done and want
to show it?
