Really? Works for me:

regression=# create group student inherit;
CREATE ROLE
regression=# create group employee inherit;
CREATE ROLE
regression=# create group "user";
CREATE ROLE
regression=# grant "user" to student;
GRANT ROLE
regression=# grant "user" to employee;
GRANT ROLE
regression=# create user joe inherit;
CREATE ROLE
regression=# grant student to joe;
GRANT ROLE
regression=# create table mytable (f1 int);
CREATE TABLE
regression=# grant select on mytable to "user";
GRANT
regression=# \c - joe
psql (8.4devel)
You are now connected to database "regression" as user "joe".
regression=> select * from mytable;
f1
----
(0 rows)

I suspect you forgot to attach the "inherit" property to the
intermediate-level group.
