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(7)].
       There is no effective difference between dropping users via this	 util‐
       ity 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  connec‐
       tion 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 exten‐
	      sion on which the server is listening for connections.

       -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

DIAGNOSTICS
       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 connec‐
       tion 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 veri‐
       fication 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
