Yes (like restricted tokens and pg_upgrade stuff we did), but I was
just waiting that we reach an agreement for the version of master
before moving on with patches for back branches.

This rebased patch looks fine for me. I am attaching as well versions
for back-branches for 9.1~9.5. In this case it is just necessary to
duplicate pgwin32_get_dynamic_tokeninfo and pgwin32_is_service to
pg_ctl.c to make things work properly.
