I don't know a lot about Windows.
First, why are you trying to use the precompiled libpq.dll you have with other libraries
than the ones that were included?
For one, I know that EDB's PostgreSQL binaries use a different C runtime (msvc*.dll)
for versions 9.3 and 9.4. Maybe that is your problem.
There is an excellent tool, Dependency Walker (http://dependencywalker.com/),
that can help you debug problems of this kind.
