+ New major version numbering (Peter Eisentraut, Tom Lane)
+
+
+ Major versions will now increase just the first number, and minor
+ releases will increase just the second number. A third number
+ will no longer be used in Postgres version numbers.
+
+
+
+
+
+ Allow the
ICU library to+ optionally be used for collation support (Peter Eisentraut)
+
+
+ The
ICU library has versioning that allows detection+ of collation changes between versions. It is enabled via configure
+ option
+ system's native collation library.

+
+
+ Automatically mark all
+ linkend="xfunc-c">PG_FUNCTION_INFO_V1 functions
+ as DLLEXPORT-ed on
+ Windows (Laurenz Albe)
+
+
+ If third-party code is using extern function
+ declarations, they should also add DLLEXPORT markers
+ to those declarations.
+
+
+
+
+
+ Allow shared memory to be dynamically allocated (Thomas Munro,
+ Robert Haas)
+
+
+
+
+
+ Add slab-like memory allocator for efficient fixed-size allocations
+ (Tomas Vondra)
+
+
+
+
+
+ Use
POSIX semaphores rather than SysV semaphores+ on
Linux and
+ class="osname">FreeBSD (Tom Lane)
+
+
+ This avoids some limits on SysV semaphore usage.
+
+
+
+
+
+ Improve support for 64-bit atomics (Andres Freund)
+
+
+
+
+
+ Enable 64-bit atomic operations on
ARM64 (Roman+ Shaposhnik)
+
+
+
+
+
+ Switch to using clock_gettime(), if available, for
+ duration measurements (Tom Lane)
+
+
+ gettimeofday() is used if clock_gettime()
+ is not available.
+
+
+
+
+
+ Add more robust random number generators to be used for
+ cryptographic secure uses (Magnus Hagander, Michael Paquier,
+ Heikki Linnakangas)

-Allow
file_fdw to read from program output as well as files (Corey Huinker, Adam Gomaa)-
-
-
-
-
-Push aggregates to foreign data wrapper servers, where possible (Jeevan
-Chalke, Ashutosh Bapat)
-
-
-This reduces the amount of data that must be passed from the foreign
-data wrapper server, and offloads aggregate computation from the
-requesting server. The
postgres_fdw is able to perform this-optimization.
-

-
-Allow push down of FULL JOIN queries containing subqueries in the
-FROM clause to foreign servers (Etsuro Fujita)
-
-
-
-
-
-Properly support
OID columns in postgres_fdw tables (Etsuro Fujita)-
-
-Previously OID columns always returned zeros.
-

-Allow
btree_gist and btree_gin to index enum types-(Andrew Dunstan)
-

-Add indexing support to
btree_gist for the UUID data type (Paul-Jungwirth)

-
-This also improves handling of infinite and NaN values.

pg_buffercache to run with fewer locks (Ivan Kartyshov)-
-
-This allows it be less disruptive when run on production systems.

-Add
pgstathashindex() function to pgstattuple to view hash index-statistics (Ashutosh Sharma)
-
-

-
-Allow
pgstattuple to use GRANT permissions (Stephen Frost)-
-
-This allows non-superusers to run these functions if permissions allow.

-Reduce locking when
pgstattuple examines hash indexes (Amit Kapila)-
-
