postgres module in msvc

Hi there and thx for reading and answering if you can

A few years ago, I wrote a pg module in C on gcc/linux. This module works fine, and I'm striving to port on windows postgres edb, I compiled the corresponding .dll wirh both mingw54 and msvc 2022, but got postgres crashes.

Do you have a better available example ?

Thx again for reading
