Why do we need these? An explanation seems in order in the shape of a
commit, or these should be removed.
Is there a different trick than the one posted at [1] to check the
stability of the proposal? I am wondering if I am missing something,
or if that's all. Alexander?

There was also a separate test (independent of bgwriter, autovacuum,
checkpointer,...) at the top of the thread: [1].
FWIW, 004_timeline_switch also failed the past month in the same way [2].
I've just tested 012_subtransactions.pl with the script I proposed at [3]
and it passed 100 iterations (because it performs $node_primary->stop;
before $node_standby->promote;, I suppose).
