Fix incorrect handling of NULL index entries in
indexed ROW() comparisons (Tom Lane)
An index search using a row comparison such as ROW(a, b) >
ROW('x', 'y') would stop upon reaching a NULL entry in
the b column, ignoring the fact that there might be
non-NULL b values associated with later values
of a.
Avoid unlikely data-loss scenarios due to renaming files without
adequate fsync() calls before and after (Michael Paquier,
Tomas Vondra, Andres Freund)
Correctly handle cases where pg_subtrans is close to XID
wraparound during server startup (Jeff Janes)
Fix corner-case crash due to trying to free localeconv()
output strings more than once (Tom Lane)
Fix parsing of affix files for ispell dictionaries
(Tom Lane)
The code could go wrong if the affix file contained any characters
whose byte length changes during case-folding, for
example I in Turkish UTF8 locales.
Avoid use of sscanf() to parse ispell
dictionary files (Artur Zakirov)
This dodges a portability problem on FreeBSD-derived platforms
(including macOS).
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)

version.

characters properly (Kyotaro Horiguchi, Robert Haas)

SECURITY LABEL (Tom Lane)
Pressing TAB after SECURITY LABEL might cause a crash
or offering of inappropriate keywords.
Make pg_ctl accept a wait timeout from the
PGCTLTIMEOUT environment variable, if none is specified on
the command line (Noah Misch)
This eases testing of slower buildfarm members by allowing them
to globally specify a longer-than-normal timeout for postmaster
startup and shutdown.
Fix incorrect test for Windows service status
in pg_ctl (Manuel Mathar)
The previous set of minor releases attempted to
fix pg_ctl to properly determine whether to send log
messages to Window's Event Log, but got the test backwards.
Fix pgbench to correctly handle the combination
of -C and -M prepared options (Tom Lane)
In PL/Perl, properly translate empty Postgres arrays into empty Perl
arrays (Alex Hunsaker)
Make PL/Python cope with function names that aren't valid Python
identifiers (Jim Nasby)
Fix multiple mistakes in the statistics returned
by contrib/pgstattuple's pgstatindex()
function (Tom Lane)
Remove dependency on psed in MSVC builds, since it's no
longer provided by core Perl (Michael Paquier, Andrew Dunstan)

(Kaliningrad, Samara, Volgograd).
