Humm, but the privilege was not granted by test1, but by the user you
were using initially. The docs state in a note that
A user can only revoke privileges that were granted directly by
that user.
I understand that this would apply to the grantor stuff being discussed
in this thread as well, but I haven't seen anyone arguing that we should
implement that for GRANT ROLE (and I asked three times if people felt it
was important and nobody answered).
