+ Fix <command>VACUUM</>'s tests to see whether it can
+ update <structfield>relfrozenxid</> (Andres Freund)
+ </para>
+
+ <para>
+ In some cases <command>VACUUM</> (either manual or autovacuum) could
+ incorrectly advance a table's <structfield>relfrozenxid</> value,
+ allowing tuples to escape freezing, causing those rows to become
+ invisible once 2^31 transactions have elapsed. The probability of
+ data loss is fairly low since multiple incorrect advancements would
+ need to happen before actual loss occurs, but it's not zero. Users
+ upgrading from release 8.4.8 or earlier are not affected, but all later
+ versions contain the bug.
+ </para>
+
+ <para>
+ The issue can be ameliorated by, after upgrading, vacuuming all tables
+ in all databases while having <link
+ linkend="guc-vacuum-freeze-table-age"><varname>vacuum_freeze_table_age</></link>
+ set to zero. This will fix any latent corruption but will not be able
+ to fix all pre-existing data errors. However, an installation can be
+ presumed safe after performing this vacuuming if it has executed fewer
+ than 2^31 update transactions in its lifetime (check this with
+ <literal>SELECT txid_current() < 2^31</>).

+ Avoid flattening a subquery whose <literal>SELECT</> list contains a

+ Fix incorrect behaviors when using a SQL-standard, simple GMT offset

+ </para>
+
+ <para>
+ In some cases, the system would use the simple GMT offset value when
+ it should have used the regular timezone setting that had prevailed
+ before the simple offset was selected. This change also causes
+ the <function>timeofday</> function to honor the simple GMT offset
+ zone.
