<para>
Fix misbehavior during recursive page split in GiST index build
(Heikki Linnakangas)
</para>
<para>
Fix a case where the location of a page downlink was incorrectly
tracked, and introduce some logic to allow recovering from such
situations rather than silently doing the wrong thing. This error
could result in incorrect answers from subsequent index searches.
It may be advisable to reindex all GiST indexes after installing
this update.

<para>
Fix edge case in btree mark/restore processing of ScalarArrayOpExpr
clauses (Peter Geoghegan)
</para>
<para>
When restoring an indexscan to a previously marked position, the
code could miss required setup steps if the scan had advanced
exactly to the end of the matches for a ScalarArrayOpExpr (that is,
an <literal>indexcol = ANY(ARRAY[])</literal>) clause. This could
result in missing some rows that should have been fetched.

Formerly these functions attempted to process the index, and might
fail in strange ways depending on what the failed <command>CREATE

Avoid improper response to shutdown signals in child processes

</para>
<para>
This fix avoids a race condition in which a child process that has
been forked off by <function>system()</function>, but hasn't yet
exec'd the intended child program, might receive and act on a signal
intended for the parent server process. That would lead to
duplicate cleanup actions being performed, which will not end well.

Avoid integer overflow when computing size of backend activity
string array (Jakub Wartak)
</para>
<para>
On 64-bit machines we will allow values
of <varname>track_activity_query_size</varname> large enough to
cause 32-bit overflow when multiplied by the allowed number of
connections. The code actually allocating the per-backend local
array was careless about this though, and allocated the array
incorrectly.

Track the dependencies of cached <command>CALL</command> statements,
and re-plan them when needed (Tom Lane)
</para>
<para>
DDL commands, such as replacement of a function that has been
inlined into a <command>CALL</command> argument, can create the need
to re-plan a <command>CALL</command> that has been cached by
PL/pgSQL. That was not happening, leading to misbehavior or strange
errors such as <quote>cache lookup failed</quote>.

Suppress assorted build-time warnings on
recent <productname>macOS</productname> (Tom Lane)
</para>
<para>
<productname>Xcode 15</productname> (released
with <productname>macOS Sonoma</productname>) changed the linker's
behavior in a way that causes many duplicate-library warnings while
building <productname>PostgreSQL</productname>. These were
harmless, but they're annoying so avoid citing the same libraries
twice. Also remove use of the <option>-multiply_defined
suppress</option> linker switch, which apparently has been a no-op
for a long time, and is now actively complained of.

<para>
Remove <literal>PHOT</literal> (Phoenix Islands Time) from the
default timezone abbreviations list (Tom Lane)
</para>
<para>
Presence of this abbreviation in the default list can cause failures
on recent Debian and Ubuntu releases, as they no longer install the
underlying tzdb entry by default. Since this is a made-up
abbreviation for a zone with a total human population of about two
dozen, it seems unlikely that anyone will miss it. If someone does,
they can put it back via a custom abbreviations file.
