pg_shadow
pg_shadow
The view pg_shadow exists for backwards compatibility: it emulates a catalog that existed in Tacnode before version It shows properties of all roles that are marked as rolcanlogin in pg_authid.
The name stems from the fact that this table should not be readable by the public since it contains passwords. pg_user is a publicly readable view on pg_shadow that blanks out the password field.
