The breakage will come when we lengthen NAMEDATALEN, which I plan to
tackle for 7.3. We will need to re-order the NOTIFY structure and put
the NAMEDATALEN string at the end of the struct so differing namedatalen
backend/clients will work. If you want to break it, 7.3 would probably
be the time to do it. :-) Users will need a recompile pre-7.3 to use
notify for 7.3 and later anyway.
