## NAME
       CREATE_USER_MAPPING - define a new mapping of a user to a foreign server

## SYNOPSIS
       CREATE USER MAPPING [ IF NOT EXISTS ] FOR { _user_name_ | USER | CURRENT_ROLE | CURRENT_USER | PUBLIC }
           SERVER _server_name_
           [ OPTIONS ( _option_ '_value_' [ , ... ] ) ]

## DESCRIPTION
       **CREATE** **USER** **MAPPING** defines a mapping of a user to a foreign server. A user mapping typically
       encapsulates connection information that a foreign-data wrapper uses together with the
       information encapsulated by a foreign server to access an external data resource.

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

## PARAMETERS
       IF NOT EXISTS
           Do not throw an error if a mapping of the given user to the given foreign server already
           exists. A notice is issued in this case. Note that there is no guarantee that the
           existing user mapping is anything like the one that would have been created.

       _user_name_
           The name of an existing user that is mapped to foreign server.  CURRENT_ROLE,
           CURRENT_USER, and USER match the name of the current user. When PUBLIC is specified, a
           so-called public mapping is created that is used when no user-specific mapping is
           applicable.

       _server_name_
           The name of an existing server for which the user mapping is to be created.

       OPTIONS ( _option_ '_value_' [, ... ] )
           This clause specifies the options of the user mapping. The options typically define the
           actual user name and password of the mapping. Option names must be unique. The allowed
           option names and values are specific to the server's foreign-data wrapper.

## EXAMPLES
       Create a user mapping for user bob, server foo:

           CREATE USER MAPPING FOR bob SERVER foo OPTIONS (user 'bob', password 'secret');

## COMPATIBILITY
       **CREATE** **USER** **MAPPING** conforms to ISO/IEC 9075-9 (SQL/MED).
