ALTER TYPE(7)                    SQL Commands                    ALTER TYPE(7)

       ALTER TYPE - change the definition of a type

       ALTER TYPE name RENAME TO new_name
       ALTER TYPE name OWNER TO new_owner
       ALTER TYPE name SET SCHEMA new_schema

       ALTER TYPE changes the definition of an existing type.

       You  must  own the type to use ALTER TYPE.  To change the schema of a type, 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 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.)

       name   The name (possibly schema-qualified) of an existing type to alter.

              The new name for the type.

              The user name of the new owner of the type.

              The new schema for the type.

       To rename a data type:

       ALTER TYPE electronic_mail RENAME TO email;

       To change the owner of the type email to joe:

       ALTER TYPE email OWNER TO joe;

       To change the schema of the type email to customers:

       ALTER TYPE email SET SCHEMA customers;

       There is no ALTER TYPE statement in the SQL standard.
