We're having some RDS performance issues and are running on postgres db_engine_version 12.17. I note that the terraform-aws-metaflow module specifies db_engine_version 11 by default. To jump to the r7g instances (from r6g) requires postgres engine version 13 or better. Are there any known issues with higher postgres db engine versions? I don't see anything in the github issues, but wanted to check here out of an abundance of caution.
