PostgreSQL 14 - Setting up Virtual machines with vagrant for postgres. Part 1
In this video, we are starting a new series on configuring highly available database management system. You will learn how to install and configure more than one Postgres's servers for high availability, continuous backup, and zero down time disaster recovery.
