   3    The view <code class="literal">collation_character_set_applicability</code>
   4    identifies which character set the available collations are
   5    applicable to.  In PostgreSQL, there is only one character set per
   6    database (see explanation
   7    in <a class="xref" href="infoschema-character-sets.html" title="35.7. character_sets">Section 35.7</a>), so this view does
   8    not provide much useful information.
