51.87. 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.
Table 51.88.
