Yes, I have noticed the failure, and waited for more data to gather while thinking about what I could do. I have not come up with anything, at least yet, so for now I have just removed the test. The thing was rather limited as-is as it was able just interact with the first transaction of REINDEX building the list of partitions. Perhaps, by using a fourth session taking a SHARE lock while another uses at least a SHARE UPDATE EXCLUSIVE lock on one of the partitions, it should be possible to make REINDEX wait in one of its inner transactions for a partition. It may be tricky to make that reliable for the buildfarm though. -- Michael
