A database so large that even a minimally empty one cannot be created from scratch in less than 10-15 minutes. This creates problems for CI, integration testing, etc

You are certainly using the wrong technology then; at a previous job I was easily spinning up 3T Oracle databases in a few minutes using COW clones on the storage array attached to VMs. They were only good for a few hundred M of changes, but that was plenty for testing.
