Does that mean that using Prisma Accelerate and Pulse with an external database will cost the same as using it with the bundled database? (Since I don’t see database-specific costs for storage, read replicas, PITR, backups)
While Prisma Postgres in in early access, yes. This is why there's no ability to change the database config right now.
However, when we release Prisma Postgres in GA (couple of months), you will be able to upgrade your postgres instance (CPU, storage, etc.) and that will be db-specific cost.
