The view <code class="structname">pg_group</code> exists for backwards
compatibility: it emulates a catalog that existed in

It shows the names and members of all roles that are marked as not
<code class="structfield">rolcanlogin</code>, which is an approximation to the set
of roles that are being used as groups.
