That seems like a reasonable thing to try. It looks like NamedLWLockTrancheRequests is copied, too. Could we used that instead of adding a new variable? My guess is that this has been broken since this code was introduced in commit c1772ad from 2016/v9.6, and AFAIK you are the first to report it, so I don't feel a tremendous amount of urgency to fix it on the back-branches. -- nathan
