DROP MATERIALIZED VIEW drops an existing materialized view. To execute this command you must be the owner of the materialized view.

IF EXISTS: Do not throw an error if the materialized view does not exist. A notice is issued in this case.
name: The name (optionally schema-qualified) of the materialized view to remove.
CASCADE: Automatically drop objects that depend on the materialized view (such as other materialized views, or regular views), and in turn all objects that depend on those objects (see Section 5.15).
RESTRICT: Refuse to drop the materialized view if any objects depend on it. This is the default.

This command will remove the materialized view called order_summary:

DROP MATERIALIZED VIEW order_summary;

DROP MATERIALIZED VIEW is a PostgreSQL extension.
