That would take care of cleaning up any scripts after the postmaster has
already quit, but what about the problem of kicking the waiting backend
off the system() call in the first place? I suppose that if we can hack
things so system() doesn't block SIGQUIT on Windows, it might be OK, at
least for the "-m immediate" case. I was hoping we could get Query
Cancel to SIGINT a system()-invoked script in a regular backend, but
that might be too much to hope for on Windows, especially if it hasn't
even got a distinction between INT and QUIT ...
