53.26. pg_shadow

pg_shadow

The view pg_shadow exists for backwards compatibility: it emulates a catalog that existed in PostgreSQL before version 8.1. 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.

Column Type Description
usename `name` (references pg_authid.rolname) User name
usesysid `oid` (references pg_authid.oid) ID of this user
usecreatedb `bool` User can create databases
usesuper `bool` User is a superuser
userepl `bool` User can initiate streaming replication and put the system in and out of backup mode.
usebypassrls `bool` User bypasses every row-level security policy, see Row Security Policies for more information.
passwd `text` Encrypted password; null if none. See pg_authid for details of how encrypted passwords are stored.
valuntil `timestamptz` Password expiry time (only used for password authentication)
useconfig `text[]` Session defaults for run-time configuration variables
