Hey thanks for taking the time to 1) answer (trying to teach) and 2) coming back to correct your answer and cite detailed explanations. Wish I could upvote more than once sometimes. I was thrilled when I learned - on this here site - about listen/notify, and then went on reading the docs and the code (pg's code is surprising easy to read when you know what you're looking for - in fact it gave me enough confidence to build my own extensions...) and felt a bit underwhelmed. Hopefully someone upgrades the whole listen/notify one day for pluggability.
