I've noticed that the comments above the PartitionedRelPruneInfo struct incorrectly document how subplan_map and subpart_map are indexed. This seems to have snuck in on 4e232364033.
Also, while reading the executor README file, I noticed that we mentioned that executor nodes are created one for one for each corresponding plan node. This is no longer completely true. Some Append / MergeAppend subnodes may be skipped when performing run-time pruning at executor startup. I thought it might be best to mention that in the README.
