[PostgreSQL 8.1.2] GRANT ALL ... role1 and relation does not exist

Hi

(...)
GRANT ALL ON TABLE customers TO role1;
or
GRANT ALL ON TABLE customers TO role1 WITH GRANT OPTION;

Login: Admin
All ok

Login: role1
I get in pgAdmin III: relation 'customers' does not exist :(

What is wrong?

Best regards,
Rafał
