For AWS RDS PostgreSQL and AWS Aurora PostgreSQL

Backup and restore need a media server with NetBackup version 10.4 or above and a local LSU.
If a backup image contains a materialized view, after the restore, you need to manually refresh the materialized view. See this article to refresh materialized views:

If the user credentials used to restore are those of an IAM user, then the database object gets restored with the same ownership as in the source database.
Ownership and privileges on an object are not restored. The user that you use for the restore, becomes the owner of all the restored database objects in the following scenarios:
- If the restored user credentials are username and password.
- If the backup image is taken by a version before NetBackup version 10.4.
