CREATE USER MAPPING(7) PostgreSQL 18.6 Documentation CREATE USER MAPPING(7)
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).
