Supabase Postgres Best Practices

This is Supabase's own collection of Postgres performance rules, organized into 8 categories and prioritized by actual impact. It covers the practical stuff you need when writing queries, designing schemas, setting up indexes, and working with RLS. The nice thing here is it's not generic Postgres advice, it's specifically tuned to Supabase's flavor and the performance patterns they've seen at scale. Useful when you're optimizing slow queries or reviewing your database setup before things get messy. With 39k stars on the parent repo and 200+ installs, it's clearly getting real use from people running production Supabase instances.
