PostgreSQL is a powerful, open-source relational database system known for its robustness and advanced features. However, as with any database system, over time, PostgreSQL can suffer from table bloat—an issue that can lead to degraded performance and increased storage costs. Table bloat occurs due to the accumulation of dead tuples that are left behind after DELETE, UPDATE, and VACUUM operations. To combat this, PostgreSQL offers the VACUUM command, but in many scenarios, it’s not sufficient to reclaim all the wasted space. This is where pg_repack comes in.
