Working with the Database Preview environment

The PostgreSQL community continuously releases new PostgreSQL version and extensions, including beta versions. This gives PostgreSQL users the opportunity to try out a new PostgreSQL version early. To learn more about the PostgreSQL community beta release process, see Beta Information in the PostgreSQL documentation. Similarly, Amazon RDS makes certain PostgreSQL beta versions available as Preview releases. This allows you to create DB instances using the Preview version and test out its features in the Database Preview Environment.

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

Keep in mind the following important limitations:

  • All DB instances 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 only use General Purpose SSD and Provisioned IOPS SSD storage.

  • You can't get help from AWS Support with DB instances. Instead, you can post your questions to the AWS‐managed Q&A community, AWS re:Post.

  • 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 M6i, R6i, M6g, M5, T3, R6g, and R5 instance types only. For more information about RDS instance classes, see DB 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.
