Re: Patch: Force Primitives

I've attached a patch that fixes setPrepareThreshold; previously setting the threshold to n would mean the n+1th query would be the first binary one, and setting it to zero meant the binary protocol would never be used. This means the first query of a statement could never use the binary protocol. The patch makes setting the threshold to n mean the nth query is binary, so setting it to 1 would make the first query use the binary protocol. The patch includes some test cases that demonstrate this.

> The discussion got stuck on weather updates with feature flags, adding a minor version number to the protocol or just wait for pg 10 to break the protocol is the correct way to go forward.
