Does it cope with the case where a trigger is doing NOTIFY, and you do
a whole-table update, therefore dumping potentially millions of
notifications in at once?
(for example a rare maintenance operation on a table which has a
listen/notify arrangement triggered by single inserts or updates)
The existing implementation copes with that just fine.
