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.
