The DROP USER statement removes one or more SQL users.
Note:
New in v20.1: Since the keywords ROLE and USER can now be used interchangeably in SQL statements for enhanced Postgres compatibility, DROP USER is now an alias for DROP ROLE.
Required privileges
New in v20.1: To drop other non-admin users, the user must have the CREATEROLE parameter set.
