Re: Looking for context around which event triggers are permitted

That's a good point, Isaac. Select into, security label, comment, etc are
all maintenance style commands but are already added to the matrix. I do
think there's a good case to include other maintenance related commands as
event triggers. Suppose you want to know the last time a table was vacuumed
or the last time a table was reindexed. If you can trigger off of these
maintenance commands, there's a lot you could build on top of postgres to
make the maintenance experience easier. Seems like a positive thing.

The code exists but they are disabled at the moment. Happy to enable those
with a patch if it's as Aleksander said. Meaning, no real reason they were
disabled other than someone thought folks wouldn't need them.
