Yeah it is ... the internal async-queue data structure assumes
null-terminated strings.  What's a lot worse, so does the
wire protocol's NotificationResponse message, as well as every
existing client that can read it.  (For instance, libpq's exposed
API for notify messages hands back the payload as a null-terminated
string.)  I don't think this is going to happen.
