ALTER VIEW changes various auxiliary properties of a view. (If you want to modify the view's defining query, use CREATE OR REPLACE VIEW.)
You must own the view to use ALTER VIEW. To change a 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 view's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the view. However, a superuser can alter ownership of any view anyway.)
The name (optionally schema-qualified) of an existing view.
Do not throw an error if the view does not exist. A notice is issued in this case.
These forms set or remove the default value for a column. A default value associated with a view column is inserted into INSERT statements on the view before the view's ON INSERT rule is applied, if the INSERT does not specify a value for the column.
The user name of the new owner of the view.
The new name for the view.
The new schema for the view.
The name of a view option to be set or reset.
The new value for a view option.
For historical reasons, ALTER TABLE can be used with views too; but the only variants of ALTER TABLE that are allowed with views are equivalent to the ones shown above.
