Let’s begin the Skytools 3 documentation effort, which is long overdue. The code is waiting for you over at github, and is stable and working. Why is it still in release candidate status, I hear you asking? Well because it’s missing updated documentation. WalMgr is the Skytools component that manages WAL shipping for you, and archiving too. It knows how to prepare your master and standby setup, how to take a base backup and push it to the standby’s system, how to archive (at the satndby) master’s WAL files as they are produced and have the standby restore from this archive.
