Thats right! Its mostly a CLI orchestration tool (mentioned in the readme), with some logging, stats and safety checks so that user/engineer can be mostly hands off during the process. Perhaps, even automate the entire process by wiring up different pg_easy_replicate commands together. We do that with Tines, where we can be fully hands off (zero touch ops) and are able to kick off upgrade with switchover for tens of DBs (one at a time for now :D).
