Hi, I was just looking at RelOptInfo's partitioning fields and noticed that all_partrels seems to be set in a couple of places but never actually referenced.
The field was added in c8434d64c - Allow partitionwise joins in more cases for PG13. Maybe it did something during the development of that patch but the code didn't end up being committed? Should we get rid of it before it's too late for PG14? David
