Postgres optimization — 70 rules (queries, indexes, RLS, concurrency). Use when writing SQL or reviewing schema.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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) ## 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 …

How to install
mdr add martineserios/thebrana/supabase-postgres@sha256:ddec449e8b87c7a0The line at the top of this page pins the label git:20260610.36508ae, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
