# 获取您的 AWS 区域中可用版本的列表 通过查询 AWS 区域并使用 AWS CLI 命令 [describe-db-engine-versions](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-engine-versions.html)，您可以获得可用作 Aurora PostgreSQL 数据库集群的升级目标的所有引擎版本列表，如下所示。 对于 Linux、macOS 或 Unix： ``` aws rds describe-db-engine-versions \ --engine aurora-postgresql \ --engine-version version-number \ --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \ --output text ``` 对于：Windows ``` aws rds describe-db-engine-versions ^ --engine aurora-postgresql ^ --engine-version version-number ^ --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^ --output text ``` 例如，要确定 Aurora PostgreSQL 版本 12.10 数据库集群的有效升级目标，请运行以下 AWS CLI 命令： 对于 Linux、macOS 或 Unix： ``` aws rds describe-db-engine-versions \ --engine aurora-postgresql \ --engine-version 12.10 \ --query 'DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}' \ --output text ``` 对于：Windows ``` aws rds describe-db-engine-versions ^ --engine aurora-postgresql ^ --engine-version 12.10 ^ --query "DBEngineVersions[*].ValidUpgradeTarget[*].{EngineVersion:EngineVersion}" ^ --output text ``` 在下表中，可以找到适用于不同 Aurora PostgreSQL 数据库版本的主要和次要版本升级目标。为了保持兼容性，并非所有版本都作为升级目标提供。Aurora PostgreSQL 在每个季度的次要版本发布中都引入了新功能和错误修复。有关 Aurora PostgreSQL 次要版本的信息，请参阅

| | 14.20 | 无 | 对于您正在考虑的任何版本，请始终检查集群数据库实例类的可用性。例如，Aurora PostgreSQL 13 不支持 `db.r4`。如果 Aurora PostgreSQL 数据库集群当前使用 db.r4 实例类，则在升级到 Aurora PostgreSQL 13 之前，需要将其修改为使用支持的数据库实例类。有关可用的 Aurora PostgreSQL 数据库实例类的更多信息，包括哪些实例类基于 Graviton2 以及哪些实例基于 Intel，请参阅 [Amazon Aurora数据库实例类](Concepts.DBInstanceClass.md)。
