Great! It interestingly didn't work as the first item on the schedule,
where I had duplicated it it to out of impatience. I guess there might
be some need of concurrent autovacuum activity or something like that.
I now luckily have a rr trace of the problem, so I hope I can narrow it
down to the original problem fairly quickly.
