It's supposed to still run under the administrative account, however,
pg_ctl will create what's called a restricted token and execute it as
that - so it will run as Administrator but without access to any
permissions received by being in the Administrators or Power Users
group for example.
You can verify it by for example attempting to COPY to a file that
only administrators have access to (access must be granted through the
group, of course)
