I clearly didn't try all single extension available out there. It's
excessively annoying to compile extensions on Windows, and also I
don't have a lot of dependencies installed so there are some that I
wasn't able to test since I'm lacking some other lib and given my
absolute lack of knowledge of that platform I didn't spent time trying
to install those.
I think I tested a dozen of "small" extensions (I'm assuming that the
big one like postgis would require too much effort to build, and they
probably already take care of Windows compatibility), and I only faced
this problem. That's maybe not a representative set, but I also doubt
that I was unlucky enough to find the few only exceptions.
