Representative engagement template — replace with a real client write-up when you have one cleared for publication.
The team had accumulated dozens of indexes over five years, several duplicating each other. We captured a week of pg_stat_user_indexes data, ranked indexes by usage, and dropped the long tail. Composite indexes on the catalog browse path replaced two single-column indexes that were never used together.
Outcomes
- Three high-traffic queries rewritten
- 14 unused / duplicate indexes safely dropped
- Storage footprint down 18%
