I created a group as Andreas said but now psql \z doesn't work anymore
It give me always a segmentation fault ... what's wrong...

postgres=> INSERT INTO pg_group VALUES ('tutti',200);
INSERT 318273 1

postgres=> CREATE USER jose IN GROUP tutti;
CREATE USER
SELECT * FROM pg_group;

groname|grosysid|grolist
-------+--------+-------
tutti | 200|
(1 row)

postgres=> GRANT ALL ON temp TO GROUP tutti;
CHANGE

postgres=> \z
$ Segmentation fault
jose'
