Avoid corruption of a btree index in the unlikely case that a failure
occurs during key truncation during a page split (Peter Geoghegan)
Avoid writing an invalid empty btree index page in the unlikely case
that a failure occurs while processing INCLUDEd columns during a page
split (Peter Geoghegan)
</para>
<para>
The invalid page would not affect normal index operations, but it
might cause failures in subsequent VACUUMs. If that has happened to
one of your indexes, recover by reindexing the index.

Make <application>initdb</application> determine the operating
system's time zone from the <filename>/etc/localtime</filename>
symbolic link, if that exists (Tom Lane)
Improve <application>initdb</application>'s handling of multiple
equivalent names for the system time zone (Tom Lane, Andrew Gierth)
</para>
<para>
This makes <application>initdb</application> more likely to select
the desired time zone string when multiple identical time zones
exist.
Make <application>initdb</application> examine
the <filename>/etc/localtime</filename> symbolic link, if that
exists, to break ties between equivalent names for the system time
zone. This makes <application>initdb</application> more likely to
select the time zone name that the user would expect when multiple
identical time zones exist. It will not change the behavior
if <filename>/etc/localtime</filename> is not a symlink to a zone
data file, nor if the time zone is determined from
the <envar>TZ</envar> environment variable.
</para>
<para>
Separately, prefer <literal>UTC</literal> over other spellings of
that time zone, when neither <envar>TZ</envar>
nor <filename>/etc/localtime</filename> provide a hint. This fixes
an annoyance introduced by <application>tzdata</application> 2019a's
change to make the <literal>UCT</literal> and <literal>UTC</literal>
zone names equivalent: <application>initdb</application> was then
preferring <literal>UCT</literal>, which almost nobody wants.
