+ <para>
+ The catalog <structname>pg_authid</structname> contains information about
+ database authorization identifiers (roles). A role subsumes the concepts
+ of <quote>users</> and <quote>groups</>. A user is essentially just a
+ role with the <structfield>rolcanlogin</> flag set. Any role (with or
+ without <structfield>rolcanlogin</>) may have other roles as members; see
+ <link linkend="catalog-pg-auth-members"><structname>pg_auth_members</structname></link>.

+ Since this catalog contains passwords, it must not be publicly readable.
+ <link linkend="view-pg-roles"><structname>pg_roles</structname></link>
