The view <code class="literal">usage_privileges</code> identifies
<code class="literal">USAGE</code> privileges granted on various kinds of
objects to a currently enabled role or by a currently enabled role.
In <span class="productname">PostgreSQL</span>, this currently applies to
collations, domains, foreign-data wrappers, foreign servers, and sequences. There is one
row for each combination of object, grantor, and grantee.
</p><p>
Since collations do not have real privileges
in <span class="productname">PostgreSQL</span>, this view shows implicit
non-grantable <code class="literal">USAGE</code> privileges granted by the
owner to <code class="literal">PUBLIC</code> for all collations. The other
object types, however, show real privileges.
</p><p>
In PostgreSQL, sequences also support <code class="literal">SELECT</code>
and <code class="literal">UPDATE</code> privileges in addition to
the <code class="literal">USAGE</code> privilege. These are nonstandard and therefore
not visible in the information schema.
