Amazon RDS for PostgreSQL now supports delayed read replicas

Amazon RDS for PostgreSQL now supports delayed read replicas, allowing you to specify a minimum time period that a replica database lags behind a source database. This feature creates a time buffer that helps protect against data loss from human errors such as accidental table drops or unintended data modifications.

In disaster recovery scenarios, you can pause replication before problematic changes are applied, resume replication up to a specific log position, and promote the replica as your new primary database. This approach enables faster recovery compared to traditional point-in-time restore operations, which can take hours for large databases.

This feature is available in all AWS Regions where RDS for PostgreSQL is offered, including the AWS GovCloud (US) Regions, at no additional cost beyond standard RDS pricing. To learn more, visit the Amazon RDS for PostgreSQL documentation.
