   This release contains a variety of fixes from 7.4.
   For information about new features in the 7.4 major release, see
   <a class="xref" href="release-7-4.html" title="E.311. Release 7.4">Section E.311</a>.

    A dump/restore is <span class="emphasis"><em>not</em></span> required for those
    running 7.4.
   </p><p>
    If you want to install the fixes in the information schema
    you need to reload it into the database.
    This is either accomplished by initializing a new cluster
    by running <code class="command">initdb</code>, or by running the following
    sequence of SQL commands in each database (ideally including
    <code class="literal">template1</code>) as a superuser in
    <span class="application">psql</span>, after installing the new release:
</p><pre class="programlisting">
DROP SCHEMA information_schema CASCADE;
\i /usr/local/pgsql/share/information_schema.sql
</pre><p>
    Substitute your installation path in the second command.
