By the way, you can see the number of wait events with "LWLOCK_STATS", right? Is this function implemented because it is necessary to know the number of waiting events for investigation? If so, is not that the number of wait events is useful information? Now, I need to rebuild to get this information and I feel inconvenience. So, how about checking the number of wait events in the view? Also, I think that it will be useful if you know the waiting time. I think that it is easy to investigate when it is clearly known how long waiting time is occupied with processing time. -- Naoki Yotsunaga
