DROPUSER(1)		PostgreSQL 9.6.3 Documentation		   DROPUSER(1)

       dropuser	- remove a PostgreSQL user account

       dropuser	[connection-option...] [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 and
	   the -i/--interactive	option is used.

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

	   Prompt for confirmation before actually removing the	user, and
	   prompt for the user name if none is specified on the	command	line.

	   Print the dropuser version and exit.

	   Do not throw	an error if the	user does not exist. A notice is
	   issued in this case.

	   Show	help about dropuser command line arguments, and	exit.

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

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

       -U 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.

	   Default connection parameters

       This utility, like most other PostgreSQL	utilities, also	uses the
       environment variables supported by libpq	(see Section 32.14,
       "Environment Variables",	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;

       createuser(1), DROP ROLE	(DROP_ROLE(7))
