We've been creating duplicate RTEs for partitioned tables just because we do so for regular inheritance parent tables. But unlike regular-inheritance parents which are themselves regular tables and thus need to be scanned, partitioned tables don't need the extra RTE. This makes the conditions for building a child RTE the same as those for building an AppendRelInfo, allowing minor simplification in expand_single_inheritance_child. Since the planner's actual processing is driven off the AppendRelInfo list, nothing much changes beyond that, we just have one fewer useless RTE entry.
