Right now, the backend just barfs withFATAL: unsupported frontend protocol
so you have to do a blind search to see what it will take.
It would probably be a good idea to improve that message to mention
exactly what range of protocol versions the backend does support.
However, this will do you little good for talking to existing backends
:-(
