cm(at)enterprisedb(dot)com, is this still in your queue, or not? I am somewhat
concerned that the 2021-11-11 releases will contain a regression if the
gharial failures remain undiagnosed. I don't know how to diagnose them
without your help. (I currently can't justify reverting the suspect bug fix
on the basis of two master-branch-only failures in one buildfarm member.)
