       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.

       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 connections.

       -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

              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 command:

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