drop_user
DROP USER(7) SQL Commands DROP USER(7)NAME
DROP USER - remove a database user account
SYNOPSIS
DROP USER name
DESCRIPTION
DROP USER removes the specified user from the database. 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 an existing user.
DIAGNOSTICS
DROP USER
The message returned if the user is successfully deleted.
ERROR: DROP USER: user "name" does not exist
This message occurs if the user name is not found.
DROP USER: user "name" owns database "name", cannot be removed
You must drop the database first or change its ownership.
NOTES
Use CREATE USER [create_user(7)] to add new users, and ALTER USER [alter_user(7)] to change a user's attributes. PostgreSQL includes a
program dropuser [dropuser(1)] that has the same functionality as this command (in fact, it calls this command) but can be run from the
command shell.
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.
