   ALTER MATERIALIZED VIEW changes various auxiliary
   properties of an existing materialized view.
  
   You must own the materialized view to use ALTER MATERIALIZED
   VIEW.  To change a materialized view's schema, you must also have
   CREATE privilege on the new schema.
   To alter the owner, you must also be a direct or indirect member of the new
   owning role, and that role must have CREATE privilege on
   the materialized view's schema.  (These restrictions enforce that altering
   the owner doesn't do anything you couldn't do by dropping and recreating the
   materialized view.  However, a superuser can alter ownership of any view
   anyway.)
  
   The statement subforms and actions available for
   ALTER MATERIALIZED VIEW are a subset of those available
   for ALTER TABLE, and have the same meaning when used for
   materialized views.  See the descriptions for ALTER TABLE
   for details.
  
nameThe name (optionally schema-qualified) of an existing materialized view.
column_nameName of a new or existing column.
extension_name
       The name of the extension that the materialized view is to depend on (or no longer
       dependent on, if NO is specified).  A materialized view
       that's marked as dependent on an extension is automatically dropped when
       the extension is dropped.
      
new_column_nameNew name for an existing column.
new_ownerThe user name of the new owner of the materialized view.
new_nameThe new name for the materialized view.
new_schemaThe new schema for the materialized view.
   To rename the materialized view foo to
   bar:
ALTER MATERIALIZED VIEW foo RENAME TO bar;
   ALTER MATERIALIZED VIEW is a
   PostgreSQL extension.
