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.
