Commit fab84c7787f25756 tried to get away without doing an actual bind(), but buildfarm results show that that doesn't get the job done. So we must really bind to the target port --- and at least on my Linux box, we need a listen() as well, or conflicts won't be detected. We rely on SO_REUSEADDR to prevent problems from starting a postmaster on the socket immediately after we've bound to it in the test code. (There may be platforms where that doesn't work too well. But fortunately, we only really care whether this works on Windows, and there the default behavior should be OK.)
