Importance of Index Maintenance

Regular index maintenance is crucial for maintaining database performance and reducing bloat. While auto vacuum helps to some extent, it won't completely eliminate the need for manual index maintenance. Even with aggressive vacuuming, some bloat will still accumulate, especially in heavily loaded systems. Observing other database systems like SQL Server, it becomes clear that index maintenance is essential. Therefore, periodically recreating indexes is necessary, as it not only reduces the frequency of bloat accumulation but also helps improve system performance.
