DROPUSER(1)      PostgreSQL Client Applications       DROPUSER(1)

NAME

     dropuser - remove a PostgreSQL user account

SYNOPSIS

     dropuser [ option... ]  [ username ]

DESCRIPTION

     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(5)].   There  is  no effective difference between
     dropping users via this utility and via  other  methods  for
     accessing the server.

OPTIONS

     dropuser accepts the following command-line arguments:

     username
          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.

     -e

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

     -i

     --interactive
          Prompt for confirmation before  actually  removing  the
          user.

     -q

     --quiet
          Do not display a response.

     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 connec-
          tions.

     -U username

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

     -W

     --password
          Force password prompt (to connect to  the  server,  not
          for the password of the user to be dropped).

ENVIRONMENT

     PGHOST

     PGPORT

     PGUSER
          Default connection parameters

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

DIAGNOSTICS

     In case of difficulty,  see  DROP  ROLE  [drop_role(5)]  and
     psql(1) for discussions of potential problems and error mes-
     sages.  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.

EXAMPLES

     To remove user joe from the default database server:

     $ dropuser joe
     DROP ROLE

     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"
     DROP ROLE
