-   Upgrading <emphasis>from</emphasis> PostgreSQL 8.3 has additional restrictions not present
-   when upgrading from later PostgreSQL releases.  For example,
-   pg_upgrade will not work for upgrading from 8.3 if a user column
-   is defined as:
-   <itemizedlist>
-    <listitem>
-     <para>
-      a <type>tsquery</> data type
-     </para>

-     </para>

-   </itemizedlist>

-   You must drop any such columns and upgrade them manually.

-   Also, the default datetime storage format changed to integer after

-  <para>
-   For Windows users, note that due to different integer datetimes settings
-   used by the graphical installer and the MSI installer, it is only
-   possible to upgrade from version 8.3 of the installer distribution to
-   version 8.4 or later of the installer distribution. It is not
-   possible to upgrade from the MSI installer to the new graphical installer.
