51.86. pg_shadow
The viewpg_shadow exists for backwards compatibility: it emulates a catalog that existed inPostgreSQL before version 8.1. It shows properties of all roles that are marked asrolcanlogin inpg_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 onpg_shadow that blanks out the password field.
