The new wire protocol is FE-BE protocol.i.e. frontend-backend prototcol. It's 
the language in which postgresql server talks to a postgresql client 

So when you use libpq in your application, it talks this protocol over a TCP/IP 
or unix domain socket, with server.

This is revamped in 7.4 to allow more functionality, efficiency and 
performance. For details, check the source..:-)
