Yeah, I'd noticed that. > Disappointingly, that turned out to be just because 10 and earlier > didn't care what the error message said. That is, you can reproduce the failure on old branches? That lets out a half-theory I'd had, which was that Andres' changes to make the backend always run its socket in nonblock mode had had something to do with it. (Those changes do represent a plausible reason why SSL_shutdown might be returning WANT_READ/WANT_WRITE; but I'm not in a hurry to add such code without evidence that it actually happens and something useful would change if we retry.) regards, tom lane
