Thank you for fixing that issue!
I've tested your fix with the modification I proposed upthread:
idle_session_timeout_enabled = false;
}
+if (rand() % 10 == 0) pg_usleep(10000);
/*
* (5) disable async signal conditions again.
and can confirm that the issue is gone. On 8749d850f~1, the test failed
on iterations 3, 3. 12 for me, but on current REL_17_STABLE, 100 test
iterations succeeded.
At the same time, mylodon confirmed my other finding at [1] and failed [2] with:
-ERROR: canceling statement due to statement timeout
+ERROR: canceling statement due to user request

Best regards,
