Setting up replication with TPA
The careful reader will note that the PostgreSQL with TPA recipe in Chapter 1, First Steps, is a good prerequisite for this recipe. In fact, TPA does not have a simple option to skip setting up replication, given that most users need it; so we had to manually delete the replication part from the initial config.yml file.
Hence, this recipe is almost identical to the PostgreSQL with TPA recipe in Chapter 1, First Steps, except that we don’t do any manual deletion.
In order to avoid wasting space in a large book, we assume that you have read that recipe already, so we don’t need to provide a detailed description of the directory structure of a TPA cluster again or an example of how a successful deploy completes.
Getting ready
This is exactly the same as the PostgreSQL with TPA recipe in Chapter 1, First Steps. Those are one-off activities, so if you did them already, then you are good to go.
