drop_user_mapping
DROP USER
MAPPING(7) PostgreSQL 9.2.7 Documentation DROP USER MAPPING(7)
NAME
DROP_USER_MAPPING - remove a user mapping for a foreign server
SYNOPSIS
DROP USER MAPPING [ IF EXISTS ] FOR { user_name | USER | CURRENT_USER | PUBLIC } SERVER server_name
DESCRIPTION
DROP USER MAPPING removes an existing user mapping from foreign server.
The owner of a foreign server can drop user mappings for that server for any user. Also, a user can drop a user mapping for his own user
name if USAGE privilege on the server has been granted to the user.
PARAMETERS
IF EXISTS
Do not throw an error if the user mapping does not exist. A notice is issued in this case.
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.
EXAMPLES
Drop a user mapping bob, server foo if it exists:
DROP USER MAPPING IF EXISTS FOR bob SERVER foo;
COMPATIBILITY
DROP USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension.
