CLASS="COMMAND"

  </P
><P
>   You must own the type to use <TT
CLASS="COMMAND"
>ALTER TYPE</TT
>.
   To change the schema of a type, 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 type's schema.  (These restrictions enforce that altering the owner
   doesn't do anything you couldn't do by dropping and recreating the type.
   However, a superuser can alter ownership of any type anyway.)
