thanks for asking! yes, this file forms the basis of an ongoing migrations file in a project, so it gets copied in and then later extended. simple and has been effective in practice.i dont do rollback migrations at all  i dont really believe in them for various reasons, including that they rarely get tested, downup migration pairs often arent idempotent etc., and are also not usually the best way of resolving bad deploys.i havent looked at versioning at all, but depesz knows his stuff, so i imagine its good. there are many other more featureful migration tools around, e.g. sqitch, and the one in this repo has much more modestminimal goals.
