DROP USER removes the specified user. It does not remove tables, views, or other objects owned by the user. If the user owns any database, an error is raised.
Parameters
name
The name of the user to remove.
Notes
PostgreSQL includes a program dropuser that has the same functionality as this command (in fact, it calls this command) but can be run from the command shell.
To drop a user who owns a database, first drop the database or change its ownership.
Examples
To drop a user account:
DROP USER jonathan;
Compatibility
The DROP USER statement is a PostgreSQL extension. The SQL standard leaves the definition of users to the implementation.
