Yep.

This one I'm not quite convinced by. You can't rely on precise counts with
pgstats and we should be able to get a better idea from somewhere more
permanent which relations succeeded? But it also doesn't do much harm, so ...

What does "explicit" mean here?

pg_stat_subscription_stats :)
(I really dislike that we have pg_stat_ stuff that's not actually stats, but
something describing the current state, but that ship has well sailed).
