Changes</h3></div></div></div><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p> Fix incorrect handling of NULL index entries in indexed <code class="literal">ROW()</code> comparisons (Tom Lane) </p><p> An index search using a row comparison such as <code class="literal">ROW(a, b) > ROW('x', 'y')</code> would stop upon reaching a NULL entry in the <code class="structfield">b</code> column, ignoring the fact that there might be non-NULL <code class="structfield">b</code> values associated with later values of <code class="structfield">a</code>. </p></li><li class="listitem"><p> Avoid unlikely data-loss scenarios due to renaming files without adequate <code class="function">fsync()</code> calls before and after (Michael Paquier, Tomas Vondra, Andres Freund) </p></li><li class="listitem"><p> Fix bug in <code class="function">json_to_record()</code> when a field of its input object contains a sub-object with a field name matching one of the requested output column names (Tom Lane) </p></li><li class="listitem"><p> Fix misformatting of negative time zone offsets by <code class="function">to_char()</code>'s <code class="literal">OF</code> format code (Thomas Munro, Tom Lane) </p></li><li class="listitem"><p> Ignore <a class="xref" href="standby-settings.html#RECOVERY-MIN-APPLY-DELAY">recovery_min_apply_delay</a> parameter until recovery has reached a consistent state (Michael Paquier) </p><p> Previously, standby servers would delay application of WAL records in response to <code class="varname">recovery_min_apply_delay</code> even while replaying the initial portion of WAL needed to make their database state valid. Since the standby is useless until it's reached a consistent database state, this was deemed unhelpful. </p></li><li class="listitem"><p> Correctly handle cases where <code class="literal">pg_subtrans</code> is close to XID wraparound during server startup (Jeff Janes) </p></li><li class="listitem"><p> Fix assorted bugs in logical decoding (Andres Freund) </p><p> Trouble cases included tuples larger than one page when replica identity is <code class="literal">FULL</code>, <code class="command">UPDATE</code>s that change a primary key within a transaction large enough to be spooled to disk, incorrect reports of <span class="quote">“<span class="quote">subxact logged without previous toplevel record</span>”</span>, and incorrect reporting of a transaction's commit time. </p></li><li class="listitem"><p> Fix planner error with nested security barrier views when the outer view has a <code class="literal">WHERE</code> clause containing a correlated subquery (Dean Rasheed) </p></li><li class="listitem"><p> Fix corner-case crash due to trying to free <code class="function">localeconv()</code> output strings more than once (Tom Lane) </p></li><li class="listitem"><p> Fix parsing of affix files for <code class="literal">ispell</code> dictionaries (Tom Lane) </p><p> The code could go wrong if the affix file contained any characters whose byte length changes during case-folding, for example <code class="literal">I</code> in Turkish UTF8 locales. </p></li><li class="listitem"><p> Avoid use of <code class="function">sscanf()</code> to parse <code class="literal">ispell</code> dictionary files (Artur Zakirov) </p><p> This dodges a portability problem on FreeBSD-derived platforms (including macOS). </p></li><li class="listitem"><p> Avoid a crash on old Windows versions (before 7SP1/2008R2SP1) with an AVX2-capable CPU and a Postgres build done with Visual Studio 2013 (Christian Ullrich) </p><p> This is a workaround for a bug in Visual Studio 2013's runtime library, which Microsoft have stated they will not fix in that version. </p></li><li class="listitem"><p> Fix <span class="application">psql</span>'s tab completion logic to handle multibyte characters properly (Kyotaro Horiguchi, Robert Haas) </p></li><li class="listitem"><p> Fix <span class="application">psql</span>'s tab completion for <code class="literal">SECURITY LABEL</code> (Tom Lane) </p><p> Pressing TAB after <code class="literal">SECURITY LABEL</code> might cause a crash or offering of inappropriate keywords. </p></li><li class="listitem"><p> Make <span class="application">pg_ctl</span> accept a wait timeout from the <code class="envar">PGCTLTIMEOUT</code> environment variable, if none is specified on the command line (Noah Misch) </p><p> This eases testing of slower buildfarm members by allowing them to globally specify a longer-than-normal timeout for postmaster startup and shutdown. </p></li><li class="listitem"><p> Fix incorrect test for Windows service status in <span class="application">pg_ctl</span> (Manuel Mathar) </p><p> The previous set of minor releases attempted to fix <span class="application">pg_ctl</span> to properly determine whether to send log messages to Window's Event Log, but got the test backwards. </p></li><li class="listitem"><p> Fix <span class="application">pgbench</span> to correctly handle the combination of <code class="literal">-C</code> and <code class="literal">-M prepared</code> options (Tom Lane) </p></li><li class="listitem"><p> In <span class="application">pg_upgrade</span>, skip creating a deletion script when the new data directory is inside the old data directory (Bruce Momjian) </p><p> Blind application of the script in such cases would result in loss of the new data directory. </p></li><li class="listitem"><p> In PL/Perl, properly translate empty Postgres arrays into empty Perl arrays (Alex Hunsaker) </p></li><li class="listitem"><p> Make PL/Python cope with function names that aren't valid Python identifiers (Jim Nasby) </p></li><li class="listitem"><p> Fix multiple mistakes in the statistics returned by <code class="filename">contrib/pgstattuple</code>'s <code class="function">pgstatindex()</code> function (Tom Lane) </p></li><li class="listitem"><p> Remove dependency on <code class="literal">psed</code> in MSVC builds, since it's no longer provided by core Perl (Michael Paquier, Andrew Dunstan) </p></li><li class="listitem"><p> Update time zone data files to <span class="application">tzdata</span> release 2016c for DST law changes in Azerbaijan, Chile, Haiti, Palestine, and Russia (Altai, Astrakhan, Kirov, Sakhalin, Ulyanovsk regions), plus historical corrections for Lithuania, Moldova, and Russia (Kaliningrad, Samara, Volgograd). </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"
