<para>
Fix multiple bugs in GiST index page split processing (Heikki
Linnakangas)
</para>
<para>
The probability of occurrence was low, but these could lead to index
corruption.
</para>
</listitem>
<listitem>
<para>
Avoid possibly accessing off the end of memory in <command>ANALYZE</>
(Noah Misch)
</para>
<para>
This fixes a very-low-probability server crash scenario.
</para>
</listitem>
<listitem>
<para>
Fix race condition in relcache init file invalidation (Tom Lane)
</para>
<para>
There was a window wherein a new backend process could read a stale init
file but miss the inval messages that would tell it the data is stale.
The result would be bizarre failures in catalog accesses, typically
<quote>could not read block 0 in file ...</> later during startup.
</para>
</listitem>
<listitem>
<para>
Fix memory leak at end of a GiST index scan (Tom Lane)
</para>
<para>
Commands that perform many separate GiST index scans, such as
verification of a new GiST-based exclusion constraint on a table
already containing many rows, could transiently require large amounts of
memory due to this leak.
</para>
</listitem>
<listitem>
<para>
Fix performance problem when constructing a large, lossy bitmap
(Tom Lane)
</para>
</listitem>
<listitem>
<para>
Fix array- and path-creating functions to ensure padding bytes are
zeroes (Tom Lane)

This avoids some situations where the planner will think that
semantically-equal constants are not equal, resulting in poor
optimization.
</para>
</listitem>
<listitem>
<para>
Work around gcc 4.6.0 bug that breaks WAL replay (Tom Lane)
</para>
<para>
This could lead to loss of committed transactions after a server crash.

Fix typo in <function>pg_srand48</> seed initialization (Andres Freund)
</para>
<para>
This led to failure to use all bits of the provided seed. This function
is not used on most platforms (only those without <function>srandom</>),
and the potential security exposure from a less-random-than-expected
seed seems minimal in any case.

Fix <application>pg_restore</>'s direct-to-database mode for
<varname>standard_conforming_strings</> (Tom Lane)
