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 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

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;
