Note: The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.
The view view_table_usage identifies all tables that are used in the query expression of a view (the SELECT statement that defines the view). A table is only included if that table is owned by a currently enabled role.
Note: System tables are not included. This should be fixed sometime.
