NAME

ALTER_USER_MAPPING - change the definition of a user mapping

SYNOPSIS

ALTER USER MAPPING FOR { user_name | USER | CURRENT_ROLE | CURRENT_USER | SESSION_USER | PUBLIC }


    SERVER server_name


    OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )

DESCRIPTION

ALTER USER MAPPING changes the definition of a user mapping.

The owner of a foreign server can alter user mappings for that server for any user. Also, a user can alter a user mapping for their own user name if USAGE privilege on the server has been granted to the user.

PARAMETERS

user_name

server_name

OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )

EXAMPLES

Change the password for user mapping bob, server foo:

ALTER USER MAPPING FOR bob SERVER foo OPTIONS (SET password 'public');

COMPATIBILITY

ALTER USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED). There is a subtle syntax issue: The standard omits the FOR key word. Since both CREATE USER MAPPING and DROP USER MAPPING use FOR in analogous positions, and IBM DB2 (being the other major SQL/MED implementation) also requires it for ALTER USER MAPPING, PostgreSQL diverges from the standard here in the interest of consistency and interoperability.
