I tried to build a DNA-inspired database. I accidentally made a Postgres index checker.

I tried to build a DNA-inspired database. I accidentally made a Postgres index checker.

Short summary

A developer built IndexPilot, an open-source tool that reviews CREATE INDEX statements in migrations by comparing them against existing indexes, pg_stat_statements query patterns, and HypoPG hypothetical plans. It returns a verdict like 'worth_benchmarking' without applying changes, making it useful for PR reviews — especially when indexes are AI-suggested. The tool ships with a no-credentials quickstart example.

  • •IndexPilot reviews proposed Postgres indexes against existing catalog and query patterns
  • •Returns verdicts (e.g. existing_overlap, worth_benchmarking) without modifying the database
  • •Designed for pull-request review, particularly for AI-generated migration suggestions

Generated with AI, which can make mistakes.
