How to detect:

Index grows disproportionately due to frequent insertions and deletions without cleanup. Fragmented indexes degrade response times by up to 40%.

Recommended action:

Monitor index bloat metrics with PgHero. Regularly run REINDEX or use pg_repack to eliminate fragmentation. Catching bloat early can improve query times up to 30%.
