Au contraire!!  One of the problems with the Unix implementation is that
you *can't* tell for sure if the target process is a postmaster.  See
past discussions about how startup occasionally fails because we get
fooled by the PID mentioned in postmaster.pid now belonging to pg_ctl or
some other Postgres-owned process.

This is a place where the Windows version can actually be better than
the Unix one.  Please fix it and stop imagining that your charter is to
duplicate a particular Unix syscall bug-for-bug.
