A non-leaf partition with a subplan that is an Append node was omitted from PlannedStmt.unprunableRelids because it was mistakenly included in PlannerGlobal.prunableRelids due to the way PartitionedRelPruneInfo.leafpart_rti_map[] is constructed. This happened when a non-leaf partition used an unflattened Append or MergeAppend. As a result, ExecGetRangeTableRelation() reported an error when called from CreatePartitionPruneState() to process the partition's own PartitionPruneInfo, since it was treated as prunable when it should not have been.
