Tie loose ends in psql's new \dP command 

* Remove one unnecessary pg_class join in SQL command.  Not needed,
  because we use a regclass cast instead.

* Doc: refer to "partitioned relations" rather than specifically tables,
  since indexes are also displayed.

* Rename "On table" column to "Table", for consistency with \di.
