Works fine for me, so you've omitted some critical bit of information.
regression=# create user x;
CREATE ROLE
regression=# create group g with user x;
CREATE ROLE
regression=# create sequence seq;
CREATE SEQUENCE
regression=# grant all on seq to group g;
GRANT
regression=# \c - x
You are now connected as new user "x".
regression=> select nextval('seq');
nextval
---------
1
(1 row)
Given that you've mentioned schemas, a couple of possibilities are that
user x doesn't have USAGE permission on the schema containing the
sequence, or that he has a different search path which is leading him
to find a different sequence altogether.
If that doesn't help, let's see the exact case (including exact error
message) instead of a uselessly-abstract summary.
