       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 line.


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


              Prompt for confirmation before actually removing the user.

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

       -h host

       --host 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

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

       -U username

       --username 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 database.

              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.



       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

       $ dropuser -p 5000 -h eden -i -e joe
       Role "joe" will be permanently removed.
       Are you sure? (y/n) y
       DROP ROLE joe;

       createuser(1), DROP ROLE [drop_role(7)]
