Restoring data from a PostgreSQL database snapshot

In the case of database incidents leading to data loss, you can use your RDS snapshot to restore a new PostgreSQL RDS. The recovered RDS will contain the same ATM database with the exact same tables and data rows that your former RDS had when you created the snapshot.

Perform the following steps for snapshot restoration:
