This skill provides a set of Postgres best practices for developers managing databases in any environment. It focuses on the critical stages of database lifecycle management, from initial schema design and column type selection to the implementation of RLS policies and migration files.
Beyond authoring, it assists in diagnosing system instability by providing guidance on EXPLAIN plans, connection exhaustion, and locking issues. It ensures that changes to tables, triggers, and database functions adhere to established stability and security standards.
