This is to handle one part of the overall problem. Below is text from
previous mail discussion due to which new handling is introduced:

-- By you
if that actually is a third bug, as seems likely, somebody with access
to a windows environment will need to deal with it."

I have tried to define the handling similar to InitDB where for
administrative users,
it re-forks itself in a restricted mode as it has to start postgres.

Do you mean to say that it should check if pg_ctl runs as an administrative
user
then do the re-fork in restricted mode.
If something else, then could you please give more detail about what is
exact expectation to handle the above issue.
