Fix WAL page header initialization at the end of archive recovery

Treat <function>to_char(..., 'TH')</> as an uppercase ordinal

Disallow <command>RESET ROLE</> and <command>RESET SESSION
AUTHORIZATION</> inside security-definer functions (Tom, Heikki)
</para>
<para>
It was previously handled as <literal>'th'</> (lowercase).
This covers a case that was missed in the previous patch that
disallowed <command>SET ROLE</> and <command>SET SESSION

Fix locale handling with plperl (Heikki)
Make <command>LOAD</> of an already-loaded loadable module

</para>
<para>
This bug could cause the servers locale to change, leading to
data corruption.
Formerly, <command>LOAD</> would attempt to unload and re-load the
module, but this is unsafe and not all that useful.

Make window function <literal>PARTITION BY</> and <literal>ORDER BY</>

</para>
<para>
In 8.4.0 these lists were parsed following the rules used for
top-level <literal>GROUP BY</> and <literal>ORDER BY</> lists.
But this was not correct per the SQL standard, and it led to possible
circularity.

</para>
<para>
They are now on the <ulink

Fix handling of whole-row references to subqueries that are within
an outer join (Tom)
</para>
<para>
An example is
<literal>SELECT COUNT(ss.*) FROM ... LEFT JOIN (SELECT ...) ss ON ...</>.
Here, <literal>ss.*</> would be treated as <literal>ROW(NULL,NULL,...)</>
for null-extended join rows, which is not the same as a simple NULL.
Now it is treated as a simple NULL.
