Synopsis
dropuser [<connection_option> ...] [-e] [-i] <role_name>
dropuser --help
dropuser --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.
-e | —echo
Echo the commands that dropuser
generates and sends to the server.
-i | —interactive
Prompt for confirmation before actually removing the role.
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"
