Sorry Ivo, my bad - I managed to gloss over the salient point for your issue in this link - you're on Windows, his Postgres was on Linux!

Compiling an extension on Windows, last time I tried many moons ago was unfortunately not successful, which involved compiling the whole pg source tree via MinGW.

Hazarding a thought - although it's discontinued, it might be worth checking out Windows Subsystem for UNIX-based Applications (SUA):
https://en.wikipedia.org/wiki/Windows_Services_for_UNIX

But I suspect anything you managed to compile with that would still be incompatible with your pg instance...

Beyond that, perhaps the gurus here have some sage advice...
