The only thing it breaks AFAIK is pg_upgrade testing because pg_upgrade
insists on setting the current directory as the socket dir. Maybe we
need a pg_upgrade option to specify the socket dir to use. Or maybe the
postmaster needs to check the length somehow before it calls
StreamServerPort() so we can give a saner error message.
