--member specifieѕ an existing role that will be given membership to the
new role (i.e., GRANT newrole TO existingrole). IMO --member-of sounds
like the new role will be given membership to the specified existing role
(i.e., GRANT existingrole TO newrole). IOW a command like

createuser newrole --member-of existingrole

would make existingrole a "member of" newrole according to \du. Perhaps
--role should be --member-of because it makes the new role a member of the
existing role.
