# AWS リージョン で使用可能なバージョンのリストを取得します。 次のように、[describe-db-engine-versions](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-engine-versions.html) AWS CLI コマンドを使用して AWS リージョン をクエリすることにより、Aurora PostgreSQL DB クラスターのアップグレードターゲットとして利用可能なすべてのエンジンバージョンのリストを取得できます。 Linux、macOS、Unix の場合: ``` aws rds describe-db-engine-versions \ --engine aurora-postgresql \ --engine-version version-number \ --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \ --output text ``` Windows の場合: ``` aws rds describe-db-engine-versions ^ --engine aurora-postgresql ^ --engine-version version-number ^ --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^ --output text ``` 例えば、Aurora PostgreSQL バージョン 12.10 DB クラスターの有効なアップグレードターゲットを特定するには、次の AWS CLI のコマンドを実行します。 Linux、macOS、Unix の場合: ``` aws rds describe-db-engine-versions \ --engine aurora-postgresql \ --engine-version 12.10 \ --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \ --output text ``` Windows の場合: ``` aws rds describe-db-engine-versions ^ --engine aurora-postgresql ^ --engine-version 12.10 ^ --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^ --output text ``` 以下の表で、さまざまな Aurora PostgreSQL DB バージョンのメジャーバージョンとマイナーバージョンの両方のアップグレードターゲットを確認できます。互換性を維持するために、すべてのバージョンがアップグレードターゲットとして提供されているわけではありません。Aurora PostgreSQL では、四半期ごとのマイナーバージョンリリースごとに新機能とバグ修正が導入されています。Aurora PostgreSQL マイナー リリースの詳細については、「[https://docs.aws.amazon.com/AmazonRDS/latest/AuroraPostgreSQLReleaseNotes/Welcome.html](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraPostgreSQLReleaseNotes/Welcome.html)」を参照してください。
