The walmgr tool is supposed to simplify file-based transaction log shipping. Back in the old days (before version 9.0), it was pretty common to use walmgr to simplify base backups. With the introduction of streaming replication, the situation seems to have changed a little.

Setting up streaming has become so easy that add-ons are not as important anymore as they used to be. Of course, this is our subjective observation, which might not be what you may have observed in the recent past.

To make sure that the scope of this book does not explode, we have decided not to include any details about walmgr in this chapter. For further information, we invite you to review the documentation directory inside the walmgr source code. It contains some easy-to-use examples as well as some background information about the replication technique.
