To design PostgreSQL tables for OLTP workloads, apply normalization, choose precise data types, and enforce constraints. This ensures data integrity and query efficiency for high-volume transactional systems.

You should denormalize a PostgreSQL schema when query performance demands it, typically for analytics workloads. This Skill provides guidance on when to model reference versus event data and when to trade normalization for speed.

Best practices for primary keys and foreign keys in PostgreSQL involve using robust constraints and sensible defaults. Concrete examples help ensure safe schema evolution and maintain referential integrity across relational models.

Partitioning large PostgreSQL event tables splits data across multiple physical tables based on specific criteria like timestamps. This advanced pattern improves query performance and manageability for large-scale analytics workloads.

PostgreSQL schema design indexing strategies target specific query patterns to optimize retrieval without sacrificing write performance. Applying these patterns ensures efficient data access across typical relational models.

You can safely evolve a PostgreSQL table schema by applying concrete examples for primary keys, foreign keys, and partitioning. This structured approach maintains data integrity while adapting to changing requirements.
