(Choose two.)
Amazon Athena
Amazon RDS

Explanations:
Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. It is not a managed database service and is not compatible with PostgreSQL.
Amazon RDS (Relational Database Service) is a managed relational database service that supports several database engines, including PostgreSQL. It handles routine database tasks like provisioning, patching, backup, recovery, and scaling.
Amazon EC2 (Elastic Compute Cloud) is a compute service that allows users to run virtual servers in the cloud. While you can run PostgreSQL on EC2 instances, it is not a managed service, requiring manual management and maintenance.
Amazon DynamoDB is a fully managed NoSQL database service. It is not compatible with PostgreSQL, which is a relational database, as it uses a different data model and query language.
Amazon Aurora is a managed relational database service that is compatible with PostgreSQL. It is designed for high availability and performance, and it offers features like automatic backups and scaling.
