Shut down the instance and prepare it for the upgrade.In major version upgrades, Amazon RDS and Aurora completes the following steps: This option is less complex than an out-of-place upgrade because it’s a feature of the managed service AWS takes care of the heavy lifting and makes multi-version upgrades seamless. In-place upgradeīoth Aurora PostgreSQL and Amazon RDS for PostgreSQL support in-place automated upgrades, which use the pg_upgrade utility. Out-of-place involves external database instance or cluster to accomplish upgrade. In-place option upgrades the database on the existing instance or cluster. There are two options to perform major version upgrade: in-place and out-of-place. B-tree indexes performance improvements, rebuild indexes concurrently.Space savings and performance gains in B-tree indexes. Improved performance for aggregates or partitioned tables.Enhanced SQL performance, conformance, and convenience.Performance gains to the vacuuming system, reducing overhead from B-trees.The following table lists some of the major features across all the versions. The following table summarizes the upgrade targets for Amazon RDS for PostgreSQL. You can use the AWS Command Line Interface (AWS CLI) as shown in the following code to find the target Aurora PostgreSQL aws rds describe-db-engine-versions -engine postgres -engine-version 10.21 -query "DBEngineVersions.ValidUpgradeTarget." -output table Alternatively, if your application is not ready for PostgreSQL 14, you may consider other major versions such as PostgreSQL 12 and PostgreSQL 13 depending on your business and application needs. Skipping major versions helps save database downtime and upgrade efforts. We recommend that you first upgrade to minor version 10.21 or greater, apply any pending operating system maintenance, and then upgrade directly to PostgreSQL 14 or greater so that you can skip intermediate major versions. Planning and executing the upgrade on your schedule allows you to determine the version that best meets your needs. However, selection of the target major version may depend on your application and business needs. We recommend upgrading all instances to PostgreSQL 14 or newer. Any remaining RDS for PostgreSQL 10.x databases will be upgraded to PostgreSQL 14 starting J00:00:01 UTC regardless of the maintenance window.Ĭhoose a target engine version for upgrade Starting Ap00:00:01 UTC, AWS may upgrade your RDS for PostgreSQL 10.x databases to PostgreSQL 14 major version during a scheduled maintenance window.Starting Janu00:00:01 UTC, AWS may upgrade your Aurora PostgreSQL 10.x databases to a newer major version.Below are the important dates for RDS and Aurora PostgreSQL 10.x end of life: The Aurora and RDS for PostgreSQL end of life dates are derived from the community end of life dates. The community PostgreSQL 10 end of life was set for November 10, 2022. For the final release dates of all versions of RDS for PostgreSQL, see RDS for PostgreSQL release calendar. For the Aurora version policy, see Amazon Aurora versions. PostgreSQL 10 will no longer receive security and bug fixes after this release. PostgreSQL 10.23 is the final release of PostgreSQL 10 major version. After the fifth year, a major version has one final minor release containing any fixes, and is then considered EOL and no longer supported. The community EOL policy is to support a major version for 5 years after its initial release. This policy allows you to make version and upgrade decisions well in advance. The PostgreSQL community releases a new major version on a yearly cadence, with a defined end of life (EOL) policy for older major versions.
