I don't understand how this can work. Surely my subscriber applications
have to listen to the same notification name that the publisher is going
to notify on (unless I am missing something about how NOTIFY/LISTEN
works). Yes I know you can construct that name dynamically prior to
issuing the NOTIFY but if you are changing the notification name then
how do the subscribers know what names to listen on? Do you have a quick
example of your suggestion?
