PostgreSQL Best Practices

Core Principles

• Leverage PostgreSQL's advanced features for robust data modeling
• Optimize queries using EXPLAIN ANALYZE and proper indexing strategies
• Use native PostgreSQL data types appropriately
• Implement proper connection pooling and resource management
• Follow PostgreSQL-specific security best practices

Schema Design

Data Types

• Use appropriate native types: UUID, JSONB, ARRAY, INET, CIDR
• Prefer TIMESTAMPTZ over TIMESTAMP for timezone-aware applications
• Use TEXT instead of VARCHAR when no length limit is needed
• Consider NUMERIC for precise decimal calculations (financial data)
• Use SERIAL or BIGSERIAL for auto-incrementing IDs, or UUID for distributed systems
