Code change in AQClient to make code compatible withe both 23ai release and future release.
So that it can query the partition info from both database versions; 23ai release, which has only ENQUEUE_INSTANCE column in user_queue_shards, and also with future releases which has OWNER_INSTANCE also in user_queue_shards.
