That can only be a solution if postmaster child processes will inherit
the lock.  (The nasty scenario is where the postmaster has died but one
or more backends are still alive --- a new postmaster attempting to
start MUST detect that and refuse to start.)  Does fork/exec preserve
lock ownership on Windows?
