Hmm, strange. I had been trying to make \bind work with extended
protocol, and my findings were that there's interactions with the code
that was added for pipeline mode(*). I put research aside to work on
other things, but intended to get back to it soon ... I'm really
surprised that it works for you here.
Maybe your tests are just not extensive enough to show that it fails.
(*) This is not actually proven, but Peter had told me that his \bind
stuff had previously worked when he first implemented it before pipeline
landed. Because that's the only significant change that has happened to
the libpq code lately, it's a reasonable hypothesis.
