I haven't had time to finalize my research about this, but the admin 
option with revoke doesn't appear to work as expected.

Here is my sample SQL for 8.2.4

create table test (x integer);
\z
create role test1 noinherit;
create role test2 noinherit;
grant select on test to test1 with grant option;
grant select on test to test2;
\z test
set role test1;
revoke select on test from test2;
\z test
set role test2;
select * from test;
reset role;
revoke all on test from test2;
revoke all on test from test1;
drop role test2;
drop role test1;
drop table test;
\q


The privilege doesn't appear to be revoked by test1 from test2.  I'm not 
sure if this is related, but I wanted to bring it up in light of the 
options we have for grantor.
