Support for Amazon RDS features and options varies across AWS Regions and specific versions of each DB engine. To identify RDS DB engine version support and availability in a given AWS Region, you can use the following sections.
Amazon RDS features are different from engine-native features and options. For more information on engine-native features and options, see Engine-native features.
Supported Regions and DB engines
Table conventions
The tables in the feature sections use these patterns to specify version numbers and level of availability:
-
Version x.y – The specific version alone is available.
-
Version x.y and higher – The specified version and all higher minor versions of its major version are supported. For example, "version 10.11 and higher" means that versions 10.11, 10.11.1, and 10.12 are available.
