## NAME
       DROP_MATERIALIZED_VIEW - remove a materialized view

## SYNOPSIS
       DROP MATERIALIZED VIEW [ IF EXISTS ] _name_ [, ...] [ CASCADE | RESTRICT ]

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

## PARAMETERS
       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 5.14).

       RESTRICT
           Refuse to drop the materialized view if any objects depend on it. This is the default.

## EXAMPLES
       This command will remove the materialized view called order_summary:

           DROP MATERIALIZED VIEW order_summary;

## COMPATIBILITY
       **DROP** **MATERIALIZED** **VIEW** is a PostgreSQL extension.
