I think you're blaming the victim. Our current theory about the cause
of this is that on Windows, WaitLatchOrSocket cannot be used to wait for
completion of a nonblocking connect() call. That seems pretty broken
independently of whether libpqwalreceiver needs the capability.
In any case, we have a draft patch, so what we should be pressing for
is for somebody to test it. Peter's not in a position to do that
(and neither am I), but anyone who can build from source on Windows
could do so.
regards, tom lane
