Working with the database preview environment

The PostgreSQL community releases new major version of PostgreSQL annually. Similarly, Amazon Aurora makes PostgreSQL major versions available as Preview releases. This allows you to create DB cluster using the Preview version and test out its features in the Database Preview Environment.

Aurora PostgreSQL DB clusters in the Database Preview Environment are functionally similar to other Aurora PostgreSQL DB clusters. However, you can't use a Preview version for production.

Keep in mind the following important limitations:

  • All DB instances and DB clusters are deleted 60 days after you create them, along with any backups and snapshots.

  • You can only create a DB instance in a virtual private cloud (VPC) based on the Amazon VPC service.

  • You can't copy a snapshot of a DB instance to a production environment.

The following options are supported by the Preview.

  • You can create DB instances using r5, r6g, r6i, r7g, r7i, r8g, x2g, t3, t4g, and db.serverless instance classes only. For more information about instance classes, see Amazon AuroraDB instance classes.

  • You can use both single-AZ and multi-AZ deployments.

  • You can use standard PostgreSQL dump and load functions to export databases from or import databases to the Database Preview Environment.
