<title>Limitations in Upgrading from PostgreSQL 8.3</title>
<para>
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>
</listitem>
<listitem>
<para>
data type <type>name</> and is not the first column
</para>
</listitem>
</itemizedlist>
</para>
<para>
You must drop any such columns and upgrade them manually.
</para>
<para>
pg_upgrade will not work if the <filename>ltree</>
contrib module is installed in a database.
</para>
<para>
pg_upgrade will require a table rebuild if:
<itemizedlist>
<listitem>
<para>
a user column is of data type <type>tsvector</type>
</para>
</listitem>
</itemizedlist>
</para>
<para>
pg_upgrade will require a reindex if:
<itemizedlist>
<listitem>
<para>
an index is of type hash or GIN
</para>
</listitem>
<listitem>
<para>
an index uses <function>bpchar_pattern_ops</>
</para>
</listitem>
</itemizedlist>
</para>
<para>
Also, the default datetime storage format changed to integer after
<productname>PostgreSQL</> 8.3. pg_upgrade will check that the datetime storage format
used by the old and new clusters match. Make sure your new cluster is
built with the configure flag <option>--disable-integer-datetimes</>.
</para>
<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.
