GRANT problem ?

Hi

I get a error message when i do an INSERT in a table (Absence_jour)
containing a SERIAL field :

ERROR: absence_jour_id_seq.nextval: you don't have permissions to set
sequence absence_jour_id_seq

It fails (with PSQL and ODBC) when i connect as a simple user (gddtest), but
i granted all privileges on the table for him
with the command GRANT ALL PRIVILEGES ON Absence_jour TO gddtest  !
It works when i connect as a superuser (the user who created the table).

Hints (maybe) : PostgreSQL 7.2 compiled on AIX 4.2 with GCC 2.95.2

Thanks
