Amazon RDS for PostgreSQL updates

Amazon RDS supports DB instances running several versions of PostgreSQL. You can specify any currently available PostgreSQL version when creating a new DB instance. You can specify the major version (such as PostgreSQL 10) and any available minor version for the specified major version. If no version is specified, Amazon RDS defaults to an available version, typically the most recent version. If a major version is specified but a minor version isn't, Amazon RDS defaults to a recent release of the major version that you specified.

To see a list of available versions, and also defaults for newly created DB instances, use the describe-db-engine-versions AWS CLI command. For example, to display the default PostgreSQL engine version, use the following command.

aws rds describe-db-engine-versions --default-only --engine postgres

To learn more about versioning policy for RDS for PostgreSQL, see Amazon RDS FAQs. For more information about PostgreSQL versions, see Versioning Policy in the PostgreSQL documentation.

Deprecation of PostgreSQL 10

On April 17, 2023, Amazon RDS plans to deprecate PostgreSQL 10. For more information, see Deprecation of PostgreSQL version 10 in the Amazon RDS User Guide. We strongly recommend that you take action as soon as possible and upgrade your PostgreSQL databases running on major version 10 to a later major version, such as version 14. For information about how to do so, see Upgrading the PostgreSQL DB engine for Amazon RDS in the Amazon RDS User Guide.

Deprecation of PostgreSQL 9.6

On March 31, 2022, Amazon RDS deprecated PostgreSQL 9.6. This extended the previously announced date of January 18, 2022 to April 26, 2022. For more information, see Deprecation of PostgreSQL version 9.6 in the Amazon RDS User Guide. We strongly recommend that you upgrade all your PostgreSQL 9.6 DB instances to PostgreSQL 12 or higher as soon as possible. For information about how to do so, see Upgrading the PostgreSQL DB engine for Amazon RDS in the Amazon RDS User Guide.

For version information on all extensions, see Extensions supported for RDS for PostgreSQL 14.

PostgreSQL version 14.6 on Amazon RDS

PostgreSQL version 14.6 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 14.6 release.

New features and enhancements

  • PostgreSQL version 14.6 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 1.4 is added.

  • The tcn extension version 1.0 is added.

  • The orafce extension is updated to 3.24.

  • The pgaudit extension is updated to 1.6.2.

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:

    • pgaudit is updated to 1.3.0

    • pg_hint_plan is updated to 1.3.2

PostgreSQL version 10.23 on Amazon RDS

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.

  • 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.
