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.

PostgreSQL version 15.5-R2 on Amazon RDS

PostgreSQL version 15.5-R2 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 15.5 release.

New features and enhancements

  • Fixed a crash in CatalogCacheComputeHashValue with dblink_connect due to a Null or invalid connection.

  • Backported run_as_owner to RPG 15:

    • Backported a security fix for the logical replication apply worker that allows regular table owners to obtain privilege escalation to the subscription owner (an rds_superuser). The logical apply worker mitigates the risk by temporarily switching the role from the subscription owner to the table owner during logical apply.

      In the cases of potential security breaches, the fix will break your existing logical replication if any table in the subscription is owned by a regular user, and there are security-restricted operations attached to the table via triggers or default expressions. We recommend that you carefully examine the operations attached to the table if you notice the logical replication is broken after the upgrade. If all of the operations are as expected and you wish to revert the behavior of the logical replication so your application can continue, you can do so by setting the new parameter rds.run_logical_replication_as_subscription_owner to true. Be aware that by doing so your logical replication will be vulnerable to the aforementioned security risk again.

  • Added rds.run_logical_replication_as_subscription_owner to the Amazon RDS parameter group.

  • Supported the AWS SDK version of the aws_s3 extension.

  • Fixed the overflow in the pg_transport extension.

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 was added.

  • The tcn extension version 1.0 was added.

  • The orafce extension was updated to version 3.24.

PostgreSQL version 13.13-R2 on Amazon RDS

New features and enhancements

  • Fixed a crash in CatalogCacheComputeHashValue with dblink_connect due to a Null or invalid connection.

  • Backported run_as_owner to RPG 13:

    • Backported a security fix for the logical replication apply worker that allows regular table owners to obtain privilege escalation to the subscription owner (an rds_superuser). The logical apply worker mitigates the risk by temporarily switching the role from the subscription owner to the table owner during logical apply.

      In the cases of potential security breaches, the fix will break your existing logical replication if any table in the subscription is owned by a regular user, and there are security-restricted operations attached to the table via triggers or default expressions. We recommend that you carefully examine the operations attached to the table if you notice the logical replication is broken after the upgrade. If all of the operations are as expected and you wish to revert the behavior of the logical replication so your application can continue, you can do so by setting the new parameter rds.run_logical_replication_as_subscription_owner to true. Be aware that by doing so your logical replication will be vulnerable to the aforementioned security risk again.

  • Added rds.run_logical_replication_as_subscription_owner to the Amazon RDS parameter group.

You can then use logical replication to continuously stream the newer data recorded after the LSN and synchronize the changes from publisher to subscriber. Specifically, it allows the customer to create a logical slot on a source RDS database, take a snapshot, restore the snapshot to a new RDS instance (target), and use the value of logical_seed_lsn() from the target instance to advance the logical slot on the source instance in order to subscribe the target to the source.

PostgreSQL version 13.9 on Amazon RDS (This version has reached the end of standard support.)

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 12.15 on Amazon RDS

PostgreSQL version 12.15 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 12.15 release.

New features and enhancements

  • Fixed a security issue involving rds_sec_override which wasn't reset after the intended usage, allowing unauthorized access to restricted tables

  • You can use logical_seed_lsn to determine the LSN at which a snapshot is taken in order to establish logical replication connection between the source and the restored target database. You can then use logical replication to continuously stream the newer data recorded after the LSN and synchronize the changes from publisher to subscriber. Specifically, it allows the customer to create a logical slot on a source RDS database, take a snapshot, restore the snapshot to a new RDS instance (target), and use the value of logical_seed_lsn() from the target instance to advance the logical slot on the source instance in order to subscribe the target to the source.

This version also includes the following changes:

  • compat-collation-for-glibc was updated to version 1.8

  • pg_cron was updated to version 1.5.2

  • pglogical was updated to version 2.4.2

For version information on all extensions, see Extensions supported for RDS for PostgreSQL 12.

PostgreSQL version 12.13 on Amazon RDS (This version has reached the end of standard support.)

PostgreSQL version 12.13 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 12.13 release.

New features and enhancements

  • PostgreSQL version 12.13 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.

  • The pgaudit extension is updated to 1.4.3.

  • The pgtap extension is updated to 1.2.0.

  • The PostGIS dependency GDAL is updated to 3.4.3.

  • The PostGIS dependency PROJ is updated to 7.0.1.

  • The wal2json extension is updated to 2.5.

  • The aws_s3 extension is updated to 1.1.

Minor versions

PostgreSQL version 11.22-R2 on Amazon RDS (This version has reached the end of standard support.)

PostgreSQL version 11.22-R2 is now available on Amazon RDS. This release contains several fixes and improvements for PostgreSQL announced in the PostgreSQL 11.22 release.

New features and enhancements

  • Backported run_as_owner to RPG 11:

    • Backported a security fix for the logical replication apply worker that allows regular table owners to obtain privilege escalation to the subscription owner (an rds_superuser). The logical apply worker mitigates the risk by temporarily switching the role from the subscription owner to the table owner during logical apply.

      In the cases of potential security breaches, the fix will break your existing logical replication if any table in the subscription is owned by a regular user, and there are security-restricted operations attached to the table via triggers or default expressions. We recommend that you carefully examine the operations attached to the table if you notice the logical replication is broken after the upgrade. If all of the operations are as expected and you wish to revert the behavior of the logical replication so your application can continue, you can do so by setting the new parameter rds.run_logical_replication_as_subscription_owner to true. Be aware that by doing so your logical replication will be vulnerable to the aforementioned security risk again.

  • Added rds.run_logical_replication_as_subscription_owner to the Amazon RDS parameter group.

  • Fixed the overflow in the pg_transport extension.

  • Removed the unsupported shared libraries from the engine binary.

PostgreSQL version 11.1 on Amazon RDS (This version has reached the end of standard support.)

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

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 10.6 on Amazon RDS (This version has reached the end of standard support.)

PostgreSQL version 10.6 contains several bug fixes for issues in release 10.5. For more information on the fixes in PostgreSQL 10.6, see the PostgreSQL documentation.

This version also includes the following changes:

  • A new rds.restrict_password_commands parameter and a new rds_password role have been introduced. When the rds.restrict_password_commands parameter is enabled, only users who have the rds_password role can make user password and password expiration changes. By restricting password-related operations to a limited set of roles, you can implement policies such as password complexity requirements from the client side. The rds.restrict_password_commands parameter is static, so it requires a database restart to change it. For more information, see Restricting password management in the Amazon RDS User Guide.

  • The logical decoding plugin wal2json has been updated to commit 9e962ba.

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.

This version also includes the following changes:

  • 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.

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.

For the complete list of extensions supported by Amazon RDS for PostgreSQL, see Extension versions for Amazon RDS for PostgreSQL.

Note

The tsearch2 extension is to be removed in the next major release. We encourage customers still using pre-8.3 text search to migrate to the equivalent built-in features. For more information about migrating, see the PostgreSQL documentation.

PostgreSQL version 10.3 on Amazon RDS (This version has reached the end of standard support.)

PostgreSQL version 10.3 contains several bug fixes for issues in release 10. For more information on the fixes in 10.3, see the PostgreSQL documentation.

Version 2.1.0 of plv8 is now available. If you use plv8 and upgrade PostgreSQL to a new plv8 version, you immediately take advantage of the new extension but the catalog metadata doesn't reflect this fact. For the steps to synchronize your catalog metadata with the new version of plv8, see Upgrading PLV8 in the Amazon RDS User Guide.

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.

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.
