PostgreSQL is a popular open source database system with a rich feature set. It is used by a variety of organizations for a variety of purposes.
One way to access PostgreSQL is through a cloud-based service, such as DigitalOcean.
This article will show you how to connect to PostgreSQL using DigitalOcean.
