I thought there was nothing particularly unreasonable about Owen's
suggestion: let users with the CREATEROLE attribute comment on any role.
I don't think COMMENT added to CREATE ROLE would be a very nice fix
(aside from being ugly, what if you want to change the comment later?).
It strikes me actually that letting members of the role comment on it
is not an amazingly good idea. They are not owners of the role in any
meaningful sense --- for instance, they can't drop it. It'd be more
reasonable and consistent to say that only superusers and holders of
CREATEROLE can do COMMENT ON ROLE.
