Installing Shield on OpenBSD

Shield is a tool for backing up and restoring PostgreSQL databases. This tutorial will guide you through installing Shield on OpenBSD.

Prerequisites

Before starting the installation process, you should ensure that the following dependencies are installed on your OpenBSD system:

• PostgreSQL

Installation Process

1. Install Git and Ruby:
