+ Release 7.4.20
+
+
+ Release date
+ 2008-06-09
+
+
+
+ This release contains a variety of fixes from 7.4.19.
+ For information about new features in the 7.4 major release, see
+ .
+
+
+
+ Migration to Version 7.4.20
+
+
+ A dump/restore is not required for those running 7.4.X.
+ However, if you are upgrading from a version earlier than 7.4.11,
+ see the release notes for 7.4.11.

+
+
+ Changes
+
+
+
+
+
+ Fix conversions between ISO-8859-5 and other encodings to handle
+ Cyrillic Yo characters (e and E with
+ two dots) (Sergey Burladyan)
+
+
+
+
+
+ Fix a few datatype input functions
+ that were allowing unused bytes in their results to contain
+ uninitialized, unpredictable values (Tom)
+
+
+
+ This could lead to failures in which two apparently identical literal
+ values were not seen as equal, resulting in the parser complaining
+ about unmatched ORDER BY and DISTINCT
+ expressions.
+
+
+
+
+
+ Fix a corner case in regular-expression substring matching
+ (substring(string from
+ pattern)) (Tom)
+
+
+
+ The problem occurs when there is a match to the pattern overall but
+ the user has specified a parenthesized subexpression and that
+ subexpression hasn't got a match. An example is
+ substring('foo' from 'foo(bar)?').
+ This should return NULL, since (bar) isn't matched, but
+ it was mistakenly returning the whole-pattern match instead (ie,
+ foo).
+
+
+
+
+
+ Fix incorrect result from ecpg's
+ PGTYPEStimestamp_sub() function (Michael)
+
+
+
+
+
+ Fix DatumGetBool macro to not fail with gcc
+ 4.3 (Tom)
+
+
+
+ This problem affects old style (V0) C functions that
+ return boolean. The fix is already in 8.3, but the need to
+ back-patch it was not realized at the time.
+
+
+
+
+
+ Fix longstanding LISTEN/NOTIFY
+ race condition (Tom)
+
+
+
+ In rare cases a session that had just executed a
+ LISTEN might not get a notification, even though
+ one would be expected because the concurrent transaction executing
+ NOTIFY was observed to commit later.
+
+
+
+ A side effect of the fix is that a transaction that has executed
+ a not-yet-committed LISTEN command will not see any
+ row in pg_listener for the LISTEN,
+ should it choose to look; formerly it would have. This behavior
+ was never documented one way or the other, but it is possible that
+ some applications depend on the old behavior.
+
+
+
+
+
+ Fix display of constant expressions in ORDER BY
+ and GROUP BY (Tom)
+
+
+
+ An explictly casted constant would be shown incorrectly. This could
+ for example lead to corruption of a view definition during
+ dump and reload.
+
+
+
+
+
+ Fix libpq to handle NOTICE messages correctly
+ during COPY OUT (Tom)
+
+
+
+ This failure has only been observed to occur when a user-defined
+ datatype's output routine issues a NOTICE, but there is no
+ guarantee it couldn't happen due to other causes.
