This shows up only with static links of libpq, correct? Or are you
building a backend function?

Yeah, it's a standard win32 library so that's not a problem.
But the fix seems wrong. If you are using a static libpq, the library
should be added whenever you link that library into your client
application. Not for every single EXE and DLL that postgres produces.
The makefiles already add it to the places in PostgreSQL where it's
needed - namely postgres.exe and libpq.dll.
