Re: PoC: history of recent vacuum/checkpoint runs (using new hooks)

Speaking of retention, it would be nice if this feature allowed users to
DELETE from the view that presented the data. That would allow for any
kind of custom config that someone could dream up.

I really don't intend / want to do that. That significantly increases
the complexity, turning an append-only file into something that's
essentially almost a regular table. Yes, even with the append-only file
there's need to be a way to deal with dropped objects, but supporting
arbitrary deletes seems much more demanding.

There should be a way to reset the stats, of course. But only a fairly
coarse one.
