DESCRIPTION

       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 DEPENDS ON EXTENSION form marks the materialized view as dependent on an extension,
       such that the materialized view will automatically be dropped if the extension is dropped.

       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 (ALTER_TABLE(7)) for details.

PARAMETERS

       name
           The name (optionally schema-qualified) of an existing materialized view.

       column_name
           Name of a new or existing column.

       extension_name
           The name of the extension that the materialized view is to depend on.

       new_column_name
           New name for an existing column.

       new_owner
           The user name of the new owner of the materialized view.

       new_name
           The new name for the materialized view.

       new_schema
           The new schema for the materialized view.

EXAMPLES

       To rename the materialized view foo to bar:

           ALTER MATERIALIZED VIEW foo RENAME TO bar;

COMPATIBILITY
