ALTER USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED).
There is a subtle syntax issue: the standard omits the FOR keyword.
Since both CREATE USER MAPPING and DROP USER MAPPING use FOR in analogous positions, Greengage DB diverges from the standard here in the interest of consistency and interoperability.
