Comprehensive performance optimization guide for Postgres, maintained by Supabase. Contains rules across 8 categories, prioritized by impact to guide automated query optimization and schema design.
When to Apply
Reference these guidelines when:
Writing SQL queries or designing schemas
Implementing indexes or query optimization
Reviewing database performance issues
Configuring connection pooling or scaling
Optimizing for Postgres-specific features
Working with Row-Level Security (RLS)
