Introducing: Postgres Best Practices

Supabase released Agent Skills for Postgres Best Practices, a collection of 30 rules across 8 categories to help AI coding agents write correct, performant Postgres code. The rules follow the Agent Skills open standard and cover critical areas like query performance, connection management, Row Level Security, schema design, and concurrency. The repository addresses common mistakes seen across hundreds of thousands of Postgres projects, such as missing indexes, RLS bypasses, and connection pool exhaustion. These best practices complement the Supabase MCP server by teaching agents proper judgment while the MCP server handles database connections and execution.
