Improve PostgreSQL performance using the pgstattuple extension

This article provides an in-depth exploration of the PostgreSQL pgstattuple extension, which offers detailed insights into database storage and performance optimization.

• pgstattuple provides low-level metrics about table and index storage, including live/dead tuple counts and space utilization
• Helps detect and manage database bloat by revealing wasted space and inefficient storage patterns
• Functions like pgstattuple and pgstattuple_approx can analyze table and index physical storage characteristics
• Offers methods to identify and resolve bloat through VACUUM, VACUUM FULL, and pg_repack operations
• Can be used to automate maintenance tasks and monitor database health

The extension is particularly useful for PostgreSQL database administrators seeking to proactively manage storage efficiency and performance in Amazon Aurora and Amazon RDS PostgreSQL environments.
