PostgreSQL’s Free Space Map (FSM) is a critical internal structure that helps the database efficiently manage and reuse space within tables, directly impacting performance and storage utilization. In this talk, we’ll demystify how FSM works, explore its role in common operations like inserts, updates, and VACUUM, and discuss practical strategies for monitoring and tuning FSM for real-world workloads. Attendees will gain a deep understanding of FSM internals, troubleshooting tips, and actionable insights to optimize their PostgreSQL deployments.
