The best way to design a PostgreSQL schema for OLTP workloads is to apply normalization, define BIGINT identity primary keys, enforce NOT NULL constraints, and implement effective indexing strategies to ensure data integrity and performance.

To choose the right PostgreSQL data types for maintainability, select types like BIGINT for identity columns, TIMESTAMPTZ for timestamps, and TEXT for strings, ensuring schema constraints align with your domain model requirements.

You need time-based partitioning in PostgreSQL schema design when managing large analytics-ready schemas or complex domain models, allowing efficient data pruning and query optimization for time-series data workloads.

PostgreSQL schema design requires MVCC-aware considerations to optimize performance, ensuring indexing strategies and constraints minimize bloat and maintain concurrency control across high-volume transaction workloads.

You enforce data integrity in PostgreSQL by defining PRIMARY KEYs for reference tables, implementing foreign key relationships, and applying explicit constraints to maintain normalized structures and prevent invalid data entry.

The limitations of normalization in complex PostgreSQL domain models include potential query performance overhead from excessive joins, requiring balanced indexing strategies and occasional denormalization for analytics-ready schemas.
