Introducing pg_port into the paths would be a bad idea, since it
would prevent restarting a postmaster with a different port number.
I think if a DBA is running multiple postmasters, it's up to him
to avoid pointing more than one of them at the same "location"
directory. (Maybe we could enforce that with lock files? Not
sure it's worth the trouble though.)
