<a name="upgrade-postgres-7.2-to-7.3" id="upgrade-postgres-7.2-to-7.3"></a>Upgrading from PostgreSQL 7.2 to
7.3</h3></div></div></div><p>An OpenACS database created in PostgreSQL 7.2 will not work
correctly in PostgreSQL 7.3. This is because 7.2 truncates function
names to 31 characters, but 7.3 does not. This does not cause
problems in 7.2, because truncation occurs both at function
creation and at function calling, so they still match. But if you
use a database created in 7.2 in 7.3, the function names in the
database remain truncated but the function calls are not, and so
they don&#39;t match. Also some functions use casting commands that
no longer work in 7.3 and these functions must be recreated.</p><p>To upgrade an OpenACS site from PostgreSQL 7.2 to 7.3, first
upgrade the kernel to 4.6.3. Then, dump the database, run the
upgrade script <code class="computeroutput">/var/lib/aolserver/<span class="replaceable"><span class="replaceable">$OPENACS_SERVICE_NAME</span></span>/bin/pg_7.2to7.3_upgrade_helper.pl</code>
on the dump file, and reply the dump. See <a class="ulink" href="http://openacs.org/forums/message-view?message_id=109337" target="_top">Forum OpenACS Q&amp;A: PG 7.2-&gt;7.3 upgrade gotcha?</a>.
