 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.
