Re: Extensibility of the PostgreSQL wire protocol

[Peter Eisentraut]

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?
