(iguana is a ppc64le (POWER9) animal)

Session "s1" was blocked but pg_isolation_test_session_is_blocked() could not determine that, either because pg_blocking_pids() somehow omitted PID 4029503 (can be emulated with "PG_RETURN_BOOL(false);" inserted at the start of pg_isolation_test_session_is_blocked()), or because "s1" was blocked somehow before reaching planner_hook (= delay_execution_planner) (can be emulated with "SELECT pg_sleep(330);" added before "SET delay_execution.post_planning_lock_id = 12345;" in the session "s1" declaration).

Not reproduced. Moreover, this is the only failure of this kind among all TestModulesCheck-C failures recorded (50+).
