NAME

       DROP_USER_MAPPING - remove a user mapping for a foreign server

SYNOPSIS

       DROP USER MAPPING [ IF EXISTS ] FOR { user_name | USER | CURRENT_USER | PUBLIC } SERVER server_name

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.

       user_name
           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.

       server_name
           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.
