The buildfarm animal parula has been sporadically failing in the partition_prune test for the past week or so. It appears like an auto-vacuum or auto-analyze has run on one of the partitions of the "ab" table, causing the plan to change. This is unexpected as the table is empty. Here we install some telemetry to find out if this is the case. This also joins in pg_index to see if something has gone wrong with the index which could result in the planner being unable to use that index. We can revert this once we've figured out the cause of the plan instability. Reported-by: Tom Lane Investigation-by: Tom Lane Discussion: https://postgr.es/m/4009739.1710878318%40sss.pgh.pa.us
