We have a our database managed by DigitalOcean and a few days ago whilst our DB was overloaded we got a peculiar error in our Rails project which after looking into it quite a bit the only thing that I believe could have explained it, is if the standby node has a different DB version than the primary node. Is this possible in DO?

Unfortunately, I don’t have access to our DO stack at work, to check what exactly happened, but this question is more about curiosity than fixing the bug since it only happened once under very strange conditions.
