## 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`

  Name of a new or existing column.

`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

`ALTER MATERIALIZED VIEW` is a PostgreSQL extension.
