NAME

6       ALTER_USER_MAPPING - change the definition of a user mapping
7

SYNOPSIS

9       ALTER USER MAPPING FOR { user_name | USER | CURRENT_ROLE | CURRENT_USER | SESSION_USER | PUBLIC }
10           SERVER server_name
11           OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
12

DESCRIPTION

14       ALTER USER MAPPING changes the definition of a user mapping.
15
16       The owner of a foreign server can alter user mappings for that server
17       for any user. Also, a user can alter a user mapping for their own user
18       name if USAGE privilege on the server has been granted to the user.
19

PARAMETERS

21       user_name
22           User name of the mapping.  CURRENT_ROLE, CURRENT_USER, and USER
23           match the name of the current user.  PUBLIC is used to match all
24           present and future user names in the system.
25
26       server_name
27           Server name of the user mapping.
28
29       OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
30           Change options for the user mapping. The new options override any
31           previously specified options.  ADD, SET, and DROP specify the
32           action to be performed.  ADD is assumed if no operation is
33           explicitly specified. Option names must be unique; options are also
34           validated by the server's foreign-data wrapper.
35

EXAMPLES

37       Change the password for user mapping bob, server foo:
38
39           ALTER USER MAPPING FOR bob SERVER foo OPTIONS (SET password 'public');

COMPATIBILITY

42       ALTER USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED). There is a
43       subtle syntax issue: The standard omits the FOR key word. Since both
44       CREATE USER MAPPING and DROP USER MAPPING use FOR in analogous
45       positions, and IBM DB2 (being the other major SQL/MED implementation)
46       also requires it for ALTER USER MAPPING, PostgreSQL diverges from the
47       standard here in the interest of consistency and interoperability.
