A company plans to migrate its database to a managed AWS service that supports PostgreSQL compatibility. Which AWS services meet this requirement? (Choose two.)

Amazon RDS (Relational Database Service) is a managed service that makes it easy to set up, operate, and scale relational databases in the cloud. It supports several database engines, including PostgreSQL, making it a direct fit for the requirement. Amazon Aurora is a relational database service built for the cloud, compatible with MySQL and PostgreSQL. It offers performance and availability comparable to commercial databases at one-tenth the cost. Therefore, both Amazon RDS and Amazon Aurora meet the requirement for a managed AWS service supporting PostgreSQL compatibility. Amazon Athena is an interactive query service that makes it easy to analyze data directly in Amazon S3 using standard SQL. It is not a managed database service. Amazon EC2 provides virtual servers (instances) in the cloud, allowing users to install and manage their own databases, but it is not a managed database service itself. Amazon DynamoDB is a fast and flexible NoSQL database service, not a relational database compatible with PostgreSQL.
