CLASS="COMMAND"
>ALTER MATERIALIZED VIEW</TT
> changes various auxiliary
properties of an existing materialized view.
</P
><P
> You must own the materialized view to use <TT
CLASS="COMMAND"
>ALTER MATERIALIZED
VIEW</TT
>. To change a materialized view's schema, you must also have
<TT
CLASS="LITERAL"
>CREATE</TT
> 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 <TT
CLASS="LITERAL"
>CREATE</TT
> 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.)
</P
><P
> The statement subforms and actions available for
<TT
CLASS="COMMAND"
>ALTER MATERIALIZED VIEW</TT
> are a subset of those available
for <TT
CLASS="COMMAND"
>ALTER TABLE</TT
>, and have the same meaning when used for
materialized views. See the descriptions for <A
