It is expected, because it's the default message when a PQexec() query
returns NULL: pqReadData() will return nothing yet no error is signed.
Of course, the "really expected" would be a sucessfull exec :-)

No, I'm not. Asynchronous libpq connections on Windows are still not
realiable (althought I read someone submitted a patch recently), so I'm
keeping synchronous queries for a while. I'm not also using any non-standard
functions; just plain PQconnectdb() and PQexec()...
