The previous coding in EXPLAIN always labeled a ModifyTable node with the name of the target table affected by its first child plan. When originally written, this was necessarily the parent table of the inheritance tree, so everything was unconfusing. But when we added NO INHERIT constraints, it became possible for the parent table to be deleted from the plan by constraint exclusion while still leaving child tables present. This led to the ModifyTable plan node being labeled with the first surviving child, which was deemed confusing. Fix it by retaining the parent table's RT index in a new field in ModifyTable.
