       dropuser - remove a PostgreSQL user account


       dropuser [connection-option...] [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 line and
           the -i/--interactive option is used.

           Echo the commands that dropuser generates and sends to the server.

           Prompt for confirmation before actually removing the user, and
           prompt for the user name if none is specified on the command line.

           Print the dropuser version and exit.

           Do not throw an error if the user does not exist. A notice is
           issued in this case.

           Show help about dropuser command line arguments, and exit.

       dropuser also accepts the following command-line arguments for
       connection parameters:

       -h host
           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.

       -p port
           Specifies the TCP port or local Unix domain socket file extension
           on which the server is listening for connections.

       -U username
           User name to connect as (not the user name to drop).

           Never issue a password prompt. If the server requires password
           authentication and a password is not available by other means such
           as a .pgpass file, the connection attempt will fail. This option
           can be useful in batch jobs and scripts where no user is present to
           enter a password.

           Force dropuser to prompt for a password before connecting to a

           This option is never essential, since dropuser will automatically
           prompt for a password if the server demands password
           authentication. However, dropuser will waste a connection attempt
           finding out that the server wants a password. In some cases it is
           worth typing -W to avoid the extra connection attempt.


           Default connection parameters

           Specifies whether to use color in diagnostic messages. Possible
           values are always, auto and never.

       This utility, like most other PostgreSQL utilities, also uses the
       environment variables supported by libpq (see Section 33.14).


       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.
           Are you sure? (y/n) y
           DROP ROLE joe;
