Dexter is an automatic index advisor for Postgres that analyzes slow queries from sources like pg_stat_statements, live activity, or log files, and recommends indexes using hypothetical indexes via HypoPG. It is a Ruby command line tool that can optionally create the recommended indexes with CREATE INDEX CONCURRENTLY.
Use cases
- find missing indexes for slow postgres queries
- automatically recommend indexes from pg_stat_statements
- analyze slow queries from postgres log files
- test hypothetical indexes without building them
- create recommended indexes concurrently on a live database
When to choose
- you run Postgres and want data-driven index recommendations
- you have pg_stat_statements or slow query logs available
- you want to safely preview index suggestions before applying them
When to avoid
- you use a database other than Postgres
- you cannot install extensions like HypoPG on the database server
- you need automatic tuning beyond indexes (e.g., query rewrites or config tuning)
