Generally, like in any other language. Write files, use calls and APIs available inside Postgres, compile it and install to postgres directory. The only one I know of as of now is https://github.com/postgrespro/rusmorph And it's not an example of a well-documented extension, unfortu- nately. Hoewever, it works. It's possible that you can find some more examples on pgxn.org Also, probably you would need to compile it with USE_PGXS=1 make with_llvm=no While the USE_PGXS=1 is a standard way to compile extension out of the postgres source tree, the with_llvm=no is a workaround of some bug in the llvm-7, that doesn't allow JIT compilation of C++ code.
