PG_SHADOW

PG_SHADOW displays the attributes of all roles marked with rolcanlogin in PG_AUTHID. Only the system administrator can access this system view.

The information in this view is basically the same as that in PG_USER. The difference is that in PG_USER, passwords are sensitive and displayed as ********.
