The only restriction (better a prerequisite) I know is that you must link
your module with libpostgres.a. The reason is that postgres.exe is in fact a
DLL so you must link your modules with its import library to be able to use
symbols from the main executable (postgres.exe). Look into test/regress to
see loadable modules in action.
