I also had a discussion with her off-list, but I could not find neither.
Additional idea is to increase the log level to make analysis easier, but not
sure what value is appropriate. Is it enough to raise to DEBUG1?

That would be an option.  Let's do that if we see another failure
after disabling autovacuum.  Another thing I have noticed is
debug_parallel_query=regress for this animal, which may encourage
parallel workers, so I have also disabled it.  Let's see first if we
get more failures after af8837a10bc7.

I've noticed another failure of the test from widowbird: [1]. But probably
it's not related to f1e251be8 directly, as widowbird failed with a similar
error before: [2]. I couldn't reproduce such failures yet, but keep
trying in the background...
