--echo

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

--interactive

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

--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:

--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 thedirectory for the Unix domain socket.

--port

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

--username

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

--no-password

Never issue a password prompt. If the server requires password authentication and a password is not available by other means suchas a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is presentto enter a password.

--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 passwordauthentication. However, dropuser will waste a connection attempt finding out that the server wants a password. In some cases itis worth typing -W to avoid the extra connection attempt.ENVIRONMENTPGHOSTPGPORTPGUSERDefault connection parametersThis utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Section 33.14).DIAGNOSTICSIn case of difficulty, see DROP ROLE (DROP_ROLE(7)) and psql(1) for discussions of potential problems and error messages. Thedatabase server must be running at the targeted host. Also, any default connection settings and environment variables used by thelibpq front-end library will apply.EXAMPLESTo remove user joe from the default database server:$ dropuser joeTo 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 joeRole "joe" will be permanently removed.Are you sure?
