Removes a database role.
dropuser [connection_option ...] [-e] [-i] role_name dropuser --help dropuser --version
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.
- The name of the role to be removed. You will be prompted for a name if not specified on the command line.
- -e | --echo
- Echo the commands that dropuser generates and sends to the server.
- -i | --interactive
- Prompt for confirmation before actually removing the role.
- -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.
