IIUC, the workaround is to force the CHECKPOINT after advancing WAL segments.
Also, we can increase the max_wal_size to avoid the checkpoint due to WAL files.
Please see attached. How do you feel?

Thank you for paying attention to the issue!
I've tested $checkpoint->query_until() and confirmed that this approach
(which is also used in 4 other tests) eliminates the failure. I haven't
observed an effect of "max_wal_size = 40MB", so I'm not sure about it.
Do you have a scenario in mind, when it could be useful for the test?
Best regards,
Alexander
