A dump/restore is not required for those running 8.0.*.
25+
This release does update the major version number of the
26+
<productname>PostgreSQL</productname> libraries so it might be
27+
necessary to re-link some user applications if they cannot
28+
find the properly-numbered shared library.

<listitem><para>New cache replacement policy <acronym>2Q</> replaces

<acronym>ARC</> (Tom)</para>
56+
<para>
57+
This was done to void a pending US patent on <acronym>ARC</>. The
58+
<acronym>2Q</> code might be a few percentage points slower than
59+
<acronym>ARC</> for busy sites. Another new cache replacement
60+
policy will appear in 8.1.
61+
</para></listitem>
62+
<listitem><para>Change the Win32 default for config variable
63+
<varname>log_destination</> to <option>eventlog</> (Magnus)</para>
64+
<para>
65+
This, by default, will send all Win32 server log output to the Win32 event
66+
logger rather than standard error.

72+
<listitem><para>Increment the major version number of all interface
73+
libraries (Bruce)</para>
74+
<para>
75+
This should have been done in 8.0.0. It is required so 7.4.X versions
76+
of PostgreSQL client applications, like <application>psql</>,
77+
can be used on the same machine as 8.0.X applications. This might require
78+
re-linking user applications that use these libraries.

<listitem><para>Do not use locale-aware versions of <function>upper()</>,
81+
<function>lower()</>, and <function>initcap()</> when the locale is <literal>C</>.
82+
(Bruce)</para>
83+
<para>
84+
This allows these functions to work on platforms that sometimes
85+
generate errors with a locale of <literal>C</> and a non-<literal>SQL_ASCII</>
86+
encoding.

<listitem><para>Enable the <varname>wal_sync_method</> variable value of
89+
<option>open_datasync</> on Win32, and make it the default for that
90+
platform. (Magnus, Bruce)</para>
91+
<para>
92+
This makes Win32 behave like other supported platforms that require the
93+
administrator to make sure that data is guarantted to be written to permanent
94+
storage after a sync operation. To turn off the write cache on Win32,
95+
from the <application>Device Manager</>, chose the drive properties,
96+
then <literal>Policies</>.

100+
operating system and the drive when doing a sync.
