Hmm.

If the user has a node that is not a standby and it does not set the GUCs to start the recovery process from a backup, the initial setup is broken. (That's the case you described.) A good UI is to detect this scenario earlier. Unfortunately, there isn't a reliable and cheap way to do it. You need to start the recovery and check if it is having some progress. (I don't have a strong opinion about requiring a standby to use this tool. It would reduce the complexity about checking if the setup has all requirements to run this tool.) -- Euler Taveira EDB https://www.enterprisedb.com/
