Setting up OmniPITR
OmniPITR is a third-party tool that consists of a set of scripts that are used to maintain and manage PostgreSQL database transaction log files, that is, WAL logs.
OmniPITR can also be used for initiating hot backups on master and slave PostgreSQL servers.
In this recipe, we are going to set up and install OmniPITR.
Getting ready
In this recipe, we are going to show how to install OmniPITR on a machine. However, this needs to be done on both the master and slave servers. For our exercise, the pg-primary serves as the master server and the pg-clone server serves as the slave server.
How to do it...
The following are the series of steps that are required to configure and install OmniPITR:
On both the master and slave machines we can install the OmniPITR as follows:
     $ git clone git://github.com/omniti-labs/omnipitr.gitIn the next step, we run a sanity check to see if the omniPITR installation goes fine on both the machines:
     $ /opt/omnipitr/bin/sanity-check...
