Changes
+
+
+
+
+
+ Fix failed to build any N-way joins
+ planner error with a full join enclosed in the right-hand side of a
+ left join (Tom Lane)
+
+
+
+
+
+ Fix incorrect handling of equivalence-class tests in multilevel
+ nestloop plans (Tom Lane)
+
+
+ Given a three-or-more-way equivalence class of variables, such
+ as X.X = Y.Y = Z.Z, it was possible for the planner to omit
+ some of the tests needed to enforce that all the variables are actually
+ equal, leading to join rows being output that didn't satisfy
+ the WHERE clauses. For various reasons, erroneous plans
+ were seldom selected in practice, so that this bug has gone undetected
+ for a long time.
+
+
+
+
+
+ Fix corner-case parser failures occurring
+ when is turned on
+ (Tom Lane)
+
+
+ An example is that SELECT (ARRAY[])::text[] gave an error,
+ though it worked without the parentheses.
+
+
+
+
+
+ Fix query-lifespan memory leak in GIN index scans (Julien Rouhaud)
+
+
+
+
+
+ Fix query-lifespan memory leak and potential index corruption hazard in
+ GIN index insertion (Tom Lane)
+
+
+ The memory leak would typically not amount to much in simple queries,
+ but it could be very substantial during a large GIN index build with
+ high maintenance_work_mem.
+
+
+
+
+
+ Fix possible misbehavior of TH, th,
+ and Y,YYY format codes in to_timestamp()
+ (Tom Lane)
+
+
+ These could advance off the end of the input string, causing subsequent
+ format codes to read garbage.
+
+
+
+
+
+ Fix dumping of rules and views in which the array
+ argument of a value operator
+ ANY (array) construct is a sub-SELECT
+ (Tom Lane)
+
+
+
+
+
+ Disallow newlines in parameter values to be set in ALTER
+ SYSTEM (Tom Lane)
+
+
+ The configuration-file parser doesn't support embedded newlines in
+ string literals, so we mustn't allow them in values to be inserted
+ by ALTER SYSTEM.
+
+
+
+
+
+ Fix ALTER TABLE ... REPLICA IDENTITY USING INDEX to
+ work properly if an index on OID is selected (David Rowley)
+
+
+
+
+
+ Avoid possible misbehavior after failed tablespace symlink removal
+ (Tom Lane)
+
+
+
+
+
+ Fix crash in logical decoding on alignment-picky platforms (Tom Lane,
+ Andres Freund)
+
+
+ The failure occurred only with a transaction large enough to spill to
+ disk and a primary-key change within that transaction.
+
+
+
+
+
+ Avoid repeated requests for feedback from receiver while shutting down
+ walsender (Nick Cleaton)
+
+
+
+
+
+ Make
pg_regress use a startup timeout from the+ PGCTLTIMEOUT environment variable, if that's set (Tom Lane)
+
+
+ This is for consistency with a behavior recently added
+ to
pg_ctl; it eases automated testing on slow machines.+
+
+
+
+
+ Fix
pg_upgrade to correctly restore extension+ membership for operator families containing only one operator class
+ (Tom Lane)
+
+
+ In such a case, the operator family was restored into the new database,
+ but it was no longer marked as part of the extension. This had no
+ immediate ill effects, but would cause later
pg_dump+ runs to emit output that would cause (harmless) errors on restore.
+
+
+
+
+
+ Fix atomic operations for PPC when using IBM's XLC compiler (Noah Misch)
+
+
+
+
+
+ Back-port 9.4-era memory-barrier code changes into 9.2 and 9.3 (Tom Lane)
+
+
+ These changes were not originally needed in pre-9.4 branches, but we
+ recently back-patched a fix that expected the barrier code to work
+ properly. Only IA64 (using icc), HPPA, and Alpha platforms are
+ affected.
+
+
+
+
+
+ Reduce the number of SysV semaphores used by a build configured with
+
+
+
+
+
+
+ Rename internal function strtoi()
+ to strtoint() to dodge a conflict with a NetBSD library
+ function (Thomas Munro)
+
+
+
+
+
+ Fix reporting of errors from bind()
+ and listen() system calls on Windows (Tom Lane)
+
+
+
+
+
+ Reduce verbosity of output while building with Microsoft Visual Studio
+ (Christian Ullrich)
+
+
+
+
+
+ Support building with Visual Studio 2015
+ (Michael Paquier, Petr Jelínek)
+
+
+ Note that builds made with VS2015 will not run on Windows versions
+ before Windows Vista.
+
+
+
+
+
+ Fix putenv() to work properly with Visual Studio 2013
+ (Michael Paquier)
+
+
+
+
+
+ Avoid possibly-unsafe use of Windows' FormatMessage()
+ function (Christian Ullrich)
+
+
+ Use the FORMAT_MESSAGE_IGNORE_INSERTS flag where
+ appropriate. No live bug is known to exist here, but it seems like a
+ good idea to be careful.
+
+
+
+
+
+ Update time zone data files to
tzdata release 2016d+ for DST law changes in Russia and Venezuela. There are new zone
+ names Europe/Kirov and Asia/Tomsk to reflect
+ the fact that these regions now have different time zone histories from
+ adjacent regions.
