Good idea!
Could it be a bug? Materialized views are a Postgres extension[1] (I always
thought they are standard.) But I'd expect them to be included when talking
about "views". Maybe they are not included because they are considered being
closer to physical tables[2] than views. Yet their dependencies would justify
inclusion in view_table_usage.
