Task of restoring a cluster from backup or cloning existing cluster into a new one was floating around for some time. It was kind of possible to achieve it by doing a lot of manual actions and very error prone. So I come up with the idea of making the way how we bootstrap a new cluster configurable. In short - we want to run a custom script instead of running initdb.
