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 for details.
