ALTER_USER_MAPPING - change the definition of a user mapping SYNOPSIS
ALTER USER MAPPING FOR { user_name | USER | CURRENT_USER | PUBLIC } SERVER server_name OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] ) DESCRIPTION
ALTER USER MAPPING changes the definition of a user mapping. The owner of a foreign server can alter user mappings for that server for any user. Also, a user can alter a user mapping for his own user name if USAGE privilege on the server has been granted to the user. PARAMETERS
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. OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] ) Change options for the user mapping. The new options override any previously specified options. ADD, SET, and DROP specify the action to be performed. ADD is assumed if no operation is explicitly specified. Option names must be unique; options are also validated by the server's foreign-data wrapper. EXAMPLES
Change the password for user mapping bob, serverfoo: ALTER USER MAPPING FOR bob SERVER foo OPTIONS (user 'bob', password 'public'); COMPATIBILITY
ALTER USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED). There is a subtle syntax issue: The standard omits the FOR key word. Since both CREATE USER MAPPING and DROP USER MAPPING use FOR in analogous positions, and IBM DB2 (being the other major SQL/MED implementation) also requires it for ALTER USER MAPPING, PostgreSQL diverges from the standard here in the interest of consistency and interoperability.

MAPPING(7) PostgreSQL 9.2.7 Documentation CREATE USER MAPPING(7) NAME
CREATE_USER_MAPPING - define a new mapping of a user to a foreign server SYNOPSIS
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 his 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 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
