Name

dropuser — remove a PostgreSQL™ user account

Synopsis

dropuser [connection-option...] [option...] [username]

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 and the -i/--interactive option is used.

-e, --echo

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

-i, --interactive

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

-V, --version

Print the dropuser version and exit.

--if-exists

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

-?, --help

Show help about dropuser command line arguments, and exit.

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 connections.

-U username, --username=username

User name to connect as (not the user name to drop).

-w, --no-password

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.

-W, --password

Force dropuser to prompt for a password before connecting to a database.

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.

Diagnostics

In case of difficulty, see 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.
