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 be able to SET ROLE to 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.

Parameters

name: The name (optionally schema-qualified) of an existing materialized view.
column_name: Name of an 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_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
