dropuser - remove a PostgreSQL user account
dropuser [ option... ] [ username ]
dropuser removes an existing PostgreSQL user. Only superusers and
users with the CREATEROLE privilege can remove PostgreSQL users. (To
remove a superuser, you must yourself be a superuser.)
dropuser is a wrapper around the SQL command DROP ROLE [drop_role(7)].
There is no effective difference between dropping users via this
utility and via other methods for accessing the server.
dropuser accepts the following command-line arguments:
Specifies the name of the PostgreSQL user to be removed. You
will be prompted for a name if none is specified on the command
--echo Echo the commands that dropuser generates and sends to the
Prompt for confirmation before actually removing the user.
Do not display a response.
dropuser also accepts the following command-line arguments for
Specifies the host name of the machine on which the server is
running. If the value begins with a slash, it is used as the
directory for the Unix domain socket.
Specifies the TCP port or local Unix domain socket file
extension on which the server is listening for connections.
User name to connect as (not the user name to drop)
Force password prompt (to connect to the server, not for the
password of the user to be dropped).
PGUSER Default connection parameters
This utility, like most other PostgreSQL utilities, also uses the
environment variables supported by libpq (see in the documentation).
In case of difficulty, see DROP ROLE [drop_role(7)] and psql(1) for
discussions of potential problems and error messages. The database
server must be running at the targeted host. Also, any default
connection settings and environment variables used by the libpq front-
end library will apply.
To remove user joe from the default database server:
$ dropuser joe
To remove user joe using the server on host eden, port 5000, with
verification and a peek at the underlying command:
$ dropuser -p 5000 -h eden -i -e joe
Role "joe" will be permanently removed.
