Two big ones:
1. Control plane to manage multi-node deployments; "works out of the box" experience to make PgDog easy to deploy and use
2. QoS (quality of service): automatically block bad queries from taking down the database
Last but not least, you get SLA-backed support from us (up to P0).
New features are broken down into two categories:
1. Sharding / running Postgres at scale: always open source.
2. Infra management / making it easy to run PgDog at scale: enterprise.
This is a remarkably open-source friendly business model. I hope it works out similarly remarkably well for you!
Thank you for the clear response!
