The short version
- Each has a real cost: Census census was folded into Fivetran Activations, per the vendor: "Previously, this was called a sync in Census", and its own pricing page redirects to Fivetran pricing rather than showing Census plans; PostgreSQL requires manual scaling across multiple machines for very large deployments
- They diverge on capability: Census covers Reverse ETL, PostgreSQL covers ACID Compliance.
