I meant 'notifications' and not NOTIFY commands.
I haven't looked at the code but picked it from a recent presentation by Addrew Dunstan. The presentation at
http://www.pgcon.org/2008/schedule/events/107.en.html looks similar.
Slide 9 says:
Events can be lost!
– If the same event occurs between two calls on
collection by a backend, it will only see one of them
– Because pg_listener has one row per (event,
listener) pair.
And I think these limitations are being remedied by the new implementation in 9.0.
