I am developinng an appliction usig Postgresql 11, installed on a UBUTU 18.14 machine. I ahve vreated a new database to do some testing on restricting access of specific users/roles to certain data. I have done the following: REVOKE ALL ON DATABASE pertest FROM employee; GRANT CONNECT ON DATABASE pertest TO employee; and I have verifed tht the user employee does exst, I have also doen a few more GRABTs to allow specific acces. But I cannot conect, or swith to user employee: stan@smokey:/etc/postgresql/11/main$ psql -U employee psql: FATAL: Peer authentication failed for user "employee" stan=> \l List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges --------+----------+----------+---------+---------+----------------------- pertest | stan | UTF8 | C.UTF-8 | C.UTF-8 | =Tc/stan + | | stan=CTc/stan employee=CTc/stan Sorrry cut and paste mangled that.
