PostgreSQL Advanced Patterns

Advanced patterns for high-performance PostgreSQL database design, querying, and optimization.

Performance Optimization

1. Effective Indexing

-- B-tree index for equality and range queries
CREATE INDEX idx_users_email ON users(email);

-- Partial index for filtered queries
CREATE INDEX idx_active_users ON users(email) WHERE active = true;

-- Composite index for multiple columns
CREATE INDEX idx_orders_user_date ON orders(user_id, created_at DESC);
