After some more testing, I've found out that it works only if the
application code uses the shared version of the C library
(msvcrt.dll)
That means compiling with the /MD or /MDd options, or in
the GUI, selecting in the project settings,
C/C++ -> Code Generation -> Use runtime library -> Multithread DLL
(or Debug Multithreaded DLL)
That's apparently not the default when creating a new application
with Visual Studio.

libpq.dll must also having been compiled with /MD as well, but
that should be the case unless the OP changed that himself
in libpq/win32.mak
