+   <span class="productname">PostgreSQL</span> is designed to be easily extensible. For
+   this reason, extensions loaded into the database can function
+   just like features that are built in. The
+   <code class="filename">contrib/</code> directory shipped with the source code
+   contains several extensions, which are described in
+   <a class="xref" href="contrib.html" title="Appendix F. Additional Supplied Modules and Extensions">Appendix F</a>.  Other extensions are developed
+   independently, like <span class="application"><a class="ulink" href="https://postgis.net/" target="_top">PostGIS</a></span>.  Even
+   <span class="productname">PostgreSQL</span> replication solutions can be developed
+   externally. For example, <span class="application"> <a class="ulink" href="https://www.slony.info" target="_top">Slony-I</a></span> is a popular
+   primary/standby replication solution that is developed independently
+   from the core project.
