ALTER USER MAPPING(7) PostgreSQL 9.6.6 Documentation ALTER USER MAPPING(7)
NAME
ALTER_USER_MAPPING - change the definition of a user mapping
SYNOPSIS
ALTER USER MAPPING FOR { user_name | USER | CURRENT_USER | SESSION_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 their 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, server foo:
ALTER USER MAPPING FOR bob SERVER foo OPTIONS (SET 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.
