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.


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


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


--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)


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



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
