Supabase's Postgres performance guide covering query, connection, security, schema, locking, data access, monitoring and advanced rules.
- What it does
- Provides a prioritized reference of Postgres performance and design rules maintained by Supabase, organized into eight categories such as query performance, connection management, security and RLS, schema design, locking, data access, monitoring and advanced features. Each rule file explains why the practice matters and shows incorrect and correct SQL examples, with optional EXPLAIN output or metrics. A compiled version of all rules is available in AGENTS.md.
- When to use it
- Use it when writing or reviewing SQL queries, designing schemas, adding indexes, tuning connection pooling, or diagnosing Postgres performance issues. It is also relevant when working with Postgres-specific features or Row-Level Security.
- Requirements
- Instructions only; no scripts are shipped. Reading the rule files requires access to the skill's own markdown documents.
