Fix failure of walsender processes to respond to shutdown signals
(Marco Nenciarini)
</para>
<para>
A missed flag update resulted in walsenders continuing to run as long
as they had a standby server connected, preventing primary-server
shutdown unless immediate shutdown mode is used.

<para>
Show foreign tables
in <structname>information_schema</>.<structname>table_privileges</>
view (Peter Eisentraut)
</para>
<para>
All other relevant <structname>information_schema</> views include
foreign tables, but this one ignored them.
</para>
<para>
Since this view definition is installed by <application>initdb</>,
merely upgrading will not fix the problem. If you need to fix this
in an existing installation, you can, as a superuser, do this
in <application>psql</>:
<programlisting>
BEGIN;
DROP SCHEMA information_schema CASCADE;
\i <replaceable>SHAREDIR</>/information_schema.sql
COMMIT;
</programlisting>
(Run <literal>pg_config --sharedir</> if you're uncertain
where <replaceable>SHAREDIR</> is.) This must be repeated in each
database to be fixed.

Clean up handling of a fatal exit (e.g., due to receipt

This situation could result in an assertion failure. In production

<para>
Correctly identify columns that are of a range type or domain type over
a composite type or domain type being searched for (Tom Lane)
</para>
<para>
Certain <command>ALTER</> commands that change the definition of a
composite type or domain type are supposed to fail if there are any
stored values of that type in the database, because they lack the
infrastructure needed to update or check such values. Previously,
these checks could miss relevant values that are wrapped inside range
types or sub-domains, possibly allowing the database to become
inconsistent.

<para>
Improve selection of compiler flags for PL/Perl on Windows (Tom Lane)
</para>
<para>
This fix avoids possible crashes of PL/Perl due to inconsistent
assumptions about the width of <type>time_t</> values.
A side-effect that may be visible to extension developers is
that <literal>_USE_32BIT_TIME_T</> is no longer defined globally
in <productname>PostgreSQL</> Windows builds. This is not expected
to cause problems, because type <type>time_t</> is not used
in any <productname>PostgreSQL</> API definitions.
