Supabase Postgres Best Practices

This is Supabase's official Postgres optimization guide packaged as a Claude skill. It covers 8 categories of performance rules, from critical query optimization and connection pooling to advanced features, with each rule including incorrect vs correct SQL examples and EXPLAIN plan analysis. You'd reach for this when writing queries, designing schemas, or debugging performance issues in Postgres or Supabase projects. The rules are prioritized by impact, which is helpful since you can focus on the critical stuff like missing indexes and connection management before diving into incremental optimizations. It's basically Supabase's internal knowledge about how to not shoot yourself in the foot with Postgres, now available to Claude for code review and generation.
