Cost-Efficiently Designing, Optimizing, and Scaling Self-Managed PostgreSQL

PostgreSQL is free, but self-managing it at scale certainly isn’t. Once you’ve committed to running PostgreSQL yourself, the cost equation shifts from licensing fees to infrastructure usage, engineering time, and operational complexity.

Too often, those costs creep in quietly. A few over-provisioned instances here. Some neglected vacuum settings there. Before long, a budget-friendly database becomes an expensive part of your stack.

The good news? Most of these costs are avoidable. With the right architectural discipline, operational practices, and tooling, PostgreSQL can deliver the performance and resilience your organization needs without draining time or resources.

This guide walks through where PostgreSQL environments most commonly result in overspending, and what technical leaders can do to control and contain these costs without compromising on reliability or scale.
