abstract
Comprehensive Postgres performance optimization guide for developers using Supabase and Postgres. Contains performance rules across 8 categories, prioritized by impact from critical (query performance, connection management) to incremental (advanced features). Each rule includes detailed explanations, incorrect vs. correct SQL examples, query plan analysis, and specific performance metrics to guide automated optimization and code generation.

Supabase Postgres Best Practices

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)

Quick Decision Tree

Problem?
├─ Slow query → query-missing-indexes, query-composite-indexes, monitor-explain-analyze
├─ Connection errors / timeouts → conn-pooling, conn-limits, conn-idle-timeout
├─ Deadlocks / long transactions → lock-short-transactions, lock-deadlock-prevention
├─ Bulk load slow → data-batch-inserts, data-upsert
├─ Table bloat / VACUUM issues → monitor-vacuum-analyze
├─ JSONB queries slow → advanced-jsonb-indexing
├─ FTS / search quality → advanced-full-text-search (pair with /postgres-semantic-search for BM25 + vector)
└─ Security / multi-tenant → security-* rules, RLS

  • /nextjs-chatbot — Chatbot orchestration, session DB, feedback, HITL
  • /ai-sdk — AI SDK patterns for backend integration

Rule Categories by Priority

Priority Category Impact Prefix
1 Query Performance CRITICAL query-
2 Connection Management CRITICAL conn-
3 Security & RLS CRITICAL security-
4 Schema Design HIGH schema-
5 Concurrency & Locking MEDIUM-HIGH lock-
6 Data Access Patterns MEDIUM data-
7 Monitoring & Diagnostics LOW-MEDIUM monitor-
8 Advanced Features LOW advanced-

How to Use

Read individual rule files for detailed explanations and SQL examples:

references/query-missing-indexes.md
references/query-partial-indexes.md
references/_sections.md

Each rule file contains:

  • Brief explanation of why it matters
  • Incorrect SQL example with explanation
  • Correct SQL example with explanation
  • Optional EXPLAIN output or metrics
  • Additional context and references
  • Supabase-specific notes (when applicable)
