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

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 or defaults to 5432.

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

-W | —password

Force a password prompt.
