dropuser

Removes a database role.

Synopsis

dropuser [<connection-option> ...] [-e] [-i] <role_name>

dropuser -? | --help 

dropuser -V | --version

Description

dropuser removes an existing role from Greenplum Database. Only superusers and users with the CREATEROLE privilege can remove roles. To remove a superuser role, you must yourself be a superuser.

dropuser is a wrapper around the SQL command DROP ROLE.

Options

role_name

The name of the role to be removed. You will be prompted for a name if not 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 role, and prompt for the role name if none is specified on the command line.

--if-exists

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

-V | --version

Print the dropuser version and exit.

-? | --help

Show help about dropuser command line arguments, and exit.

Connection Options

-h host | --host=host

The host name of the machine on which the Greenplum master database server is running. If not specified, reads from the environment variable PGHOST or defaults to localhost.

-p port | --port=port

The TCP port on which the Greenplum master database server is listening for connections. If not specified, reads from the environment variable PGPORT or defaults to 5432.

-U username | --username=username

The database role name to connect as. If not specified, reads from the environment variable PGUSER or defaults to the current system role name.

-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 a password prompt.

Examples

To remove the role joe using default connection options:

dropuser joe
DROP ROLE

To remove the role joe using connection options, with verification, and a peek at the underlying command:

dropuser -p 54321 -h masterhost -i -e joe
Role "joe" will be permanently removed.
Are you sure? (y/n) y
DROP ROLE "joe"
DROP ROLE
