NAME
       DROP USER MAPPING - remove a user mapping for a foreign server


SYNOPSIS
       DROP USER MAPPING [ IF EXISTS ] FOR { username | USER | CURRENT_USER | PUBLIC } SERVER servername


DESCRIPTION
       DROP USER MAPPING removes an existing user mapping from foreign server.

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

PARAMETERS
       IF EXISTS
              Do not throw an error if the user mapping does not exist. A notice is issued in this case.

       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.

EXAMPLES
       Drop a user mapping bob, server foo if it exists:

       DROP USER MAPPING IF EXISTS FOR bob SERVER foo;


COMPATIBILITY
       DROP USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension.
