Is the reason that we don't close it before unlinking the pid file? We can't close the logfile, as it is opened by CMD, not by the postgres process. (Postmaster is started by the command "CMD.EXE /C postgres ... >logfile".) So it is closed by the CMD shell after the postgres process exits and the postgres can't control this (as a child process).
