DROPUSER(1)						  PostgreSQL Client Applications					       DROPUSER(1)

NAME

       dropuser - remove a PostgreSQL user account

SYNOPSIS

       dropuser [ options... ] [ username ]

DESCRIPTION

       dropuser  removes an existing PostgreSQL user and the databases which that user owned.  Only users with usesuper set in the pg_shadow table
       can destroy PostgreSQL users.

       dropuser is a shell script wrapper around the SQL command DROP USER [drop_user(7)] via the PostgreSQL interactive terminal  psql(1).  Thus,
       there  is  nothing  special about removing users via this or other methods. This means that the psql must be found by the script and that a
       database server is running at the targeted host. Also, any default settings and environment variables  available  to  psql  and	the  libpq
       front-end library do apply.

OPTIONS

       dropuser accepts the following command-line arguments:

       username
	      Specifies the name of the PostgreSQL user to be removed.	This name must exist in the PostgreSQL installation.  You will be prompted
	      for a name if none is specified on the command line.

       -e

       --echo Echo the queries 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.

       createuser 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 host begins with a slash, it is used as the directory  for
	      the Unix domain socket.

       -p port

       --port port
	      Specifies the Internet TCP/IP 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)

       -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

       DROP USER
	      All is well.

       dropuser: deletion of user "username" failed
	      Something went wrong. The user was not removed.

       If there is an error condition, the backend error message will be displayed.  See DROP USER [drop_user(7)] and psql(1) for possibilities.

EXAMPLES

       To remove user joe from the default database server:

       $ dropuser joe
       DROP USER

       To remove user joe using the postmaster on host eden, port 5000, with verification and a peek at the underlying query:

       $ dropuser -p 5000 -h eden -i -e joe
       User "joe" and any owned databases will be permanently deleted.
       Are you sure? (y/n) y
       DROP USER "joe"
       DROP USER
