I have another question after thinking about that for awhile: is there
any security concern there? On Unix-oid systems, we expect the kernel
to restrict who can do a kill() on a postgres process. If there's any
similar restriction on who can send to that named pipe in the Windows
version, it's not obvious from the code. Do we have/need any
restriction there?
