Sure. "idle" here means that the backend is done with the current
command from the client. I think the OP's problem largely stems from
trying to do two transactions in one simple-query message, which is
an abuse of that feature to begin with. (We've discussed taking away
the ability to do that altogether, and while I've resisted that on
backwards-compatibility grounds, it might well happen someday.)
