Really, why? I thought this is a purely Windows specific problem.

Just replacing PQexec() with PQsendQuery() is pretty straightforward, we
could put that replacement in a file in port/win32. Replacing
PQconnectdb() is more complicated because you need to handle connection
timeout. I suggest that we only add the replacement for PQexec(), and
live with the situation for PQconnectdb(), that covers 99% of the
scenarios anyway.
