- The custom image is a saved snapshot of one created using the standard image.
Why should the use of one type of VM image versus another cause pg_restore to hallucinate the duplicate records?
To tie the other comments to your description: you took/have a snapshot of the base image after you created the database and added some records to it. Nothing wrong here - you just need to decide how you want to deal with the situation.
Sorry, but to be clear/clarify - you must be using an RDS snapshot as well as an EC2 snapshot, a fresh built RDS cluster isn’t going to be complaining about things (especially the database) existing.
