PostgreSQL version 13.9 on Amazon RDS

PostgreSQL version 13.9 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 13.9 release .

New features and enhancements

• PostgreSQL version 13.9 added support for the tcn ("triggered change notification") extension which generates notification events on table changes via a trigger function called triggered_change_notification . The tcn extension is useful for applications using drivers which support asynchronous notification. This makes it possible to notify all clients if the contents of a table have been changed, enabling them to take appropriate action in near-real time, such as updating a table cache or information display.

  However, such functionality should only be used with care as it makes all data changes on the table available to all clients (including unprivileged users) through the notification events when they listen on the tcn channel. It is the user’s responsibility to avoid using tcn trigger on a table with sensitive data to avoid information leakage.

  This version includes the following changes:

  • The seg extension version 1.3 is added.

  • The tcn extension version 1.0 is added.

  • The orafce extension is updated to 3.24.

              PostgreSQL version 11.1 on Amazon RDS (Deprecated)

              PostgreSQL version 11.1 contains several improvements that were announced in PostgreSQL 11.1 released! This version includes SQL stored procedures that enable embedded transactions within a procedure. This version also includes major improvements to partitioning and parallelism and many useful performance improvements. For example, by using a non-null constant for a column default, you can now use an ALTER TABLE command to add a column without causing a table rewrite.

              PostgreSQL version 11.1 contains several bug fixes for issues in release 11. For complete details, see the PostgreSQL release 11.1 documentation . Some changes in this version include the following:

              Partitioning – Partitioning improvements include support for hash partitioning, enabling creation of a default partition, and dynamic row movement to another partition based on the key column update.

              Performance – Performance improvements include parallelism while creating indexes, materialized views, hash joins, and sequential scans to make the operations perform better.

              Stored procedures – SQL stored procedures now added support embedded transactions.

              Support for Just-In-Time (JIT) capability – RDS for PostgreSQL 11 instances are created with JIT capability, speeding evaluation of expressions. To enable JIT capability, set the jit parameter to 1 in the PostgreSQL parameter group for the database.

              Segment size – The write-ahead logging (WAL) segment size has been changed from 16 MB to 64 MB.

              Autovacuum improvements – To provide valuable logging, the parameter rds.force_autovacuum_logging is ON by default in conjunction with the log_autovacuum_min_duration parameter set to 10 seconds. To increase autovacuum effectiveness, the values for the autovacuum_max_workers and autovacuum_vacuum_cost_limit parameters are computed based on host memory capacity to provide larger default values.

              Improved transaction timeout – The parameter idle_in_transaction_session_timeout is set to 24 hours. Any session that has been idle more than 24 hours is terminated.

              Performance metrics – The pg_stat_statements extension is included in shared_preload_libraries by default. This avoids having to reboot the instance immediately after creation. However, this functionality still requires you to run the statement CREATE EXTENSION pg_stat_statements; . Also, track_io_timing is enabled by default to add more granular data to pg_stat_statements .

              The tsearch2 extension is no longer supported – If your application uses tsearch2 functions, update it to use the equivalent functions provided by the core PostgreSQL engine. For more information about the tsearch2 extension, see PostgreSQL tsearch2 .

              The chkpass extension is no longer supported – For more information about the chkpass extension, see PostgreSQL chkpass .

              Extension updates for RDS for PostgreSQL 11.1 include the following:

              PostgreSQL version 10.23 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 10.23 release .

              New features and enhancements

              • PostgreSQL version 10.23 added support for the tcn ("triggered change notification") extension which generates notification events on table changes via a trigger function called triggered_change_notification . The tcn extension is useful for applications using drivers which support asynchronous notification. This makes it possible to notify all clients if the contents of a table have been changed, enabling them to take appropriate action in near-real time, such as updating a table cache or information display.

                However, such functionality should only be used with care as it makes all data changes on the table available to all clients (including unprivileged users) through the notification events when they listen on the tcn channel. It is the user’s responsibility to avoid using tcn trigger on a table with sensitive data to avoid information leakage.

                This version includes the following changes:

                • The seg extension version 1.1 is added.

                • The tcn extension version 1.0 is added.

                  Support for PostgreSQL 10 Logical Replication using the native publication and subscription framework. RDS for PostgreSQL databases can function as both publishers and subscribers. You can specify replication to other PostgreSQL databases at the database-level or at the table-level. With logical replication, the publisher and subscriber databases need not be physically identical (block-to-block) to each other. This allows for use cases such as data consolidation, data distribution, and data replication across different database versions for 10.4 and above. For more information, see Performing logical replication for Amazon RDS for PostgreSQL in the Amazon RDS User Guide .

                  The temporary file size limitation is user-configurable. You require the rds_superuser role to modify the temp_file_limit parameter.

                  Update of the GDAL library, which is used by the PostGIS extension. See Managing spatial data with the PostGIS extension in the Amazon RDS User Guide .

                  Update of the ip4r extension to version 2.1.1.

                  Update of the pg_repack extension to version 1.4.3. See Working with the pg_repack extension in the Amazon RDS User Guide .

                  Update of the plv8 extension to version 2.1.2.

                  PostgreSQL version 10.1 contains several bug fixes for issues in release 10. For more information on the fixes in 10.1, see the PostgreSQL documentation and the PostgreSQL 10 community announcement .

                  For information on upgrading the engine version for your PostgreSQL DB instance, see Upgrading the PostgreSQL DB engine for Amazon RDS in the Amazon RDS User Guide .

                  PostgreSQL version 10.1 includes the following changes:

                  Declarative table partitioning – PostgreSQL 10 adds table partitioning to SQL syntax and native tuple routing.

                  Parallel queries – When you create a new PostgreSQL 10.1 instance, parallel queries are enabled for the default.postgres10 parameter group. The parameter max_parallel_workers_per_gather is set to 2 by default, but you can modify it to support your specific workload requirements.

                  Support for the international components for unicode (ICU) – You can use the ICU library to provide explicitly versioned collations. Amazon RDS for PostgreSQL 10.1 is compiled with ICU version 60.2. For more information about ICU implementation in PostgreSQL, see Collation support .

                  Huge pages – Huge pages is a feature of the Linux kernel that uses multiple page size capabilities of modern hardware architectures. Amazon RDS for PostgreSQL supports huge pages with a global configuration parameter. When you create a new PostgreSQL 10.1 instance with RDS, the huge_pages parameter is set to "on" for the default.postgres10 parameter group. You can modify this setting to support your specific workload requirements.

                  Extension plv8 update – plv8 is a procedural language that you can use to write functions in JavaScript that you can then call from SQL. This release of PostgreSQL supports version 2.1.0 of plv8.

                  Renaming of xlog and location – In PostgreSQL version 10 the abbreviation "xlog" has changed to "wal", and the term "location" has changed to "lsn". For more information, see https://www.postgresql.org/docs/10/static/release-10.html#id-1.11.6.8.4 .

                  tsearch2 extension – Amazon RDS continues to provide the tsearch2 extension in PostgreSQL version 10, but is to remove it in the next major version release. If your application uses tsearch2 functions update it to use the equivalent functions the core engine provides. For more information see tsearch2 in the PostgreSQL documentation.
