The catalog <code class="structname">pg_auth_members</code> shows the membership
relations between roles. Any non-circular set of relationships is allowed.

Because user identities are cluster-wide,
<code class="structname">pg_auth_members</code>
is shared across all databases of a cluster: there is only one
copy of <code class="structname">pg_auth_members</code> per cluster, not
one per database.
