Getting a list of available versions in your Amazon Web Services Region - Amazon Aurora
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Getting a list of available versions in your Amazon Web Services Region

You can get a list of all engine versions available as upgrade targets for your Aurora PostgreSQL DB cluster by querying your Amazon Web Services Region using the describe-db-engine-versions Amazon CLI command, as follows.

For Linux, macOS, or Unix:

aws rds describe-db-engine-versions \
  --engine aurora-postgresql \
  --engine-version version-number \
  --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \
  --output text

For Windows:

aws rds describe-db-engine-versions ^
  --engine aurora-postgresql ^
  --engine-version version-number ^
  --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^
  --output text

For example, to identify the valid upgrade targets for an Aurora PostgreSQL version 12.10 DB cluster, run the following Amazon CLI command:

For Linux, macOS, or Unix:

aws rds describe-db-engine-versions \
  --engine aurora-postgresql \
  --engine-version 12.10 \
  --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \
  --output text

For Windows:

aws rds describe-db-engine-versions ^
  --engine aurora-postgresql ^
  --engine-version 12.10 ^
  --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^
  --output text

In the following table, you can find both major and minor version upgrade targets for different Aurora PostgreSQL DB versions. To maintain compatibility, not all versions are offered as upgrade targets. Aurora PostgreSQL introduces new features and bug fixes with each quarterly minor version release. For information about Aurora PostgreSQL minor releases, see the Release Notes for Aurora PostgreSQL.

For any version that you're considering, always check the availability of your cluster's DB instance class. For example, db.r4 isn't supported for Aurora PostgreSQL 13. If your Aurora PostgreSQL DB cluster currently uses a db.r4 instance class, you need to move to db.r5 before trying to upgrade. For more information about DB instance classes, including which ones are Graviton2-based and which ones are Intel-based, see Amazon Aurora DB instance classes.
