Supabase Postgres Best Practices

A comprehensive ruleset from Supabase covering eight categories of Postgres optimization, from query performance and connection pooling to RLS security and schema design. Each rule includes side-by-side incorrect and correct SQL examples with explanations, so you're not just getting theory. The priority system is smart: it separates critical issues like missing indexes from lower-impact advanced features, which helps when you're triaging performance problems. Most useful when you're writing queries that need to scale or reviewing schema designs before they become production headaches. The fact that it's maintained by Supabase means it reflects real patterns they've seen cause problems at scale, not just textbook advice.
