Changes</h3></div></div></div><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p> Fix <code class="literal">ERRORDATA_STACK_SIZE exceeded</code> crash that occurred on Windows when using UTF-8 database encoding and a different client encoding (Tom) </p></li><li class="listitem"><p> Fix <code class="command">ALTER TABLE ADD COLUMN ... PRIMARY KEY</code> so that the new column is correctly checked to see if it's been initialized to all non-nulls (Brendan Jurd) </p><p> Previous versions neglected to check this requirement at all. </p></li><li class="listitem"><p> Fix possible <code class="command">CREATE TABLE</code> failure when inheriting the <span class="quote">“<span class="quote">same</span>”</span> constraint from multiple parent relations that inherited that constraint from a common ancestor (Tom) </p></li><li class="listitem"><p> Fix <code class="function">pg_get_ruledef()</code> to show the alias, if any, attached to the target table of an <code class="command">UPDATE</code> or <code class="command">DELETE</code> (Tom) </p></li><li class="listitem"><p> Fix GIN bug that could result in a <code class="literal">too many LWLocks taken</code> failure (Teodor) </p></li><li class="listitem"><p> Avoid possible crash when decompressing corrupted data (Zdenek Kotala) </p></li><li class="listitem"><p> Repair two places where SIGTERM exit of a backend could leave corrupted state in shared memory (Tom) </p><p> Neither case is very important if SIGTERM is used to shut down the whole database cluster together, but there was a problem if someone tried to SIGTERM individual backends. </p></li><li class="listitem"><p> Fix conversions between ISO-8859-5 and other encodings to handle Cyrillic <span class="quote">“<span class="quote">Yo</span>”</span> characters (<code class="literal">e</code> and <code class="literal">E</code> with two dots) (Sergey Burladyan) </p></li><li class="listitem"><p> Fix several datatype input functions, notably <code class="function">array_in()</code>, that were allowing unused bytes in their results to contain uninitialized, unpredictable values (Tom) </p><p> This could lead to failures in which two apparently identical literal values were not seen as equal, resulting in the parser complaining about unmatched <code class="literal">ORDER BY</code> and <code class="literal">DISTINCT</code> expressions. </p></li><li class="listitem"><p> Fix a corner case in regular-expression substring matching (<code class="literal">substring(<em class="replaceable"><code>string</code></em> from <em class="replaceable"><code>pattern</code></em>)</code>) (Tom) </p><p> The problem occurs when there is a match to the pattern overall but the user has specified a parenthesized subexpression and that subexpression hasn't got a match. An example is <code class="literal">substring('foo' from 'foo(bar)?')</code>. This should return NULL, since <code class="literal">(bar)</code> isn't matched, but it was mistakenly returning the whole-pattern match instead (ie, <code class="literal">foo</code>). </p></li><li class="listitem"><p> Update time zone data files to <span class="application">tzdata</span> release 2008c (for DST law changes in Morocco, Iraq, Choibalsan, Pakistan, Syria, Cuba, and Argentina/San_Luis) </p></li><li class="listitem"><p> Fix incorrect result from <span class="application">ecpg</span>'s <code class="function">PGTYPEStimestamp_sub()</code> function (Michael) </p></li><li class="listitem"><p> Fix broken GiST comparison function for <code class="filename">contrib/tsearch2</code>'s <code class="type">tsquery</code> type (Teodor) </p></li><li class="listitem"><p> Fix possible crashes in <code class="filename">contrib/cube</code> functions (Tom) </p></li><li class="listitem"><p> Fix core dump in <code class="filename">contrib/xml2</code>'s <code class="function">xpath_table()</code> function when the input query returns a NULL value (Tom) </p></li><li class="listitem"><p> Fix <code class="filename">contrib/xml2</code>'s makefile to not override <code class="literal">CFLAGS</code> (Tom) </p></li><li class="listitem"><p> Fix <code class="literal">DatumGetBool</code> macro to not fail with <span class="application">gcc</span> 4.3 (Tom) </p><p> This problem affects <span class="quote">“<span class="quote">old style</span>”</span> (V0) C functions that return boolean. The fix is already in 8.3, but the need to back-patch it was not realized at the time. </p></li></ul></div></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="release-8-2-9.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="release.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="release-8-2-7.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">E.220.
