It's strange but after having tried it, it doesn't work ?

pg_dump says :

CREATE ROLE tableowner;
ALTER ROLE tableowner WITH NOSUPERUSER INHERIT NOCREATEROLE NOCREATEDB
NOLOGIN;
GRANT tableowner TO mycolleague GRANTED BY postgres;
GRANT tableowner TO postgres GRANTED BY postgres;

My table seems to be correct :

bw_rma=# \dt abc.testtable
Liste des relations
Schéma | Nom | Type | Propriétaire
--------+------------+-------+--------------
abc | testtable | table | tableowner
(1 ligne)

When I login as "mycolleague" :
ALTER TABLE abc.testtable ADD COLUMN field integer;

What is wrong in what I do ?

Thanks a lot for any help...
