Offhand, that seems about enough, but I'm just beginning to explore.
Chances are, event triggers will end up somewhere near the top of the
release announcements, so we should have a consistent message about what
to do with them and how to use them. If for now, we say, we only
support writing them in PL/pgSQL, and here is how to do that, and here
are some examples, that's fine. But currently, it's not quite clear.
Surely you had some use cases in mind when you set out to implement
this. What were they, and where are we now in relation to them?
