CREATE USER MAPPING -- define a new mapping of a user to a foreign serverSynopsis
CREATE USER MAPPING FOR { user_name | USER | 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
user_name
-
The name of an existing user that is mapped to foreign server.
CURRENT_USER
andUSER
match the name of the current user. WhenPUBLIC
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');
