NAME

       ALTER USER MAPPING - change the definition of a user mapping

SYNOPSIS

       ALTER USER MAPPING FOR { username | USER | CURRENT_USER | PUBLIC }
           SERVER servername
           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 his own user name if USAGE privilege on the server has
       been granted to the user.

PARAMETERS

       username
              User name of the mapping. CURRENT_USER and USER match the name of the current user.
              PUBLIC is used to match all present and future user names in the system.

       servername
              Server name of the user mapping.

       OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
              Change options for the user  mapping.  The  new  options  override  any  previously
              specified  options.  ADD,  SET, and DROP specify the action to be performed. ADD is
              assumed if no operation is explicitly  specified.  Option  names  must  be  unique;
              options are also validated by the server's foreign-data wrapper.

EXAMPLES

       Change the password for user mapping bob, server foo:

       ALTER USER MAPPING FOR bob SERVER foo OPTIONS (user 'bob', 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.
