Can it assist with database security?

Yes, it includes patterns for implementing Row-Level Security (RLS) policies to control data access at the engine level.

Does this skill help with performance for very large tables?

Yes, it provides strategies for declarative partitioning (Range, List, Hash) and BRIN indexing, which are ideal for tables exceeding 100 million rows.

What are the common PostgreSQL 'gotchas' this skill prevents?

It specifically addresses unquoted identifier casing, the lack of automatic foreign key indexing, and the nuances of NULLs in unique constraints.

Why does this skill prefer BIGINT over UUID for primary keys?

BIGINT GENERATED ALWAYS AS IDENTITY is preferred for performance and storage efficiency in most cases; UUID is recommended only when global uniqueness or opacity is required.

How does it handle semi-structured data?

It provides best practices for using JSONB and GIN indexing, allowing for flexible schemas while maintaining query performance.

Designs high-performance, normalized PostgreSQL schemas using industry best practices for indexing, data types, and scaling.

The PostgreSQL Schema Architect skill transforms Claude into a senior database engineer, providing expert guidance on designing robust and efficient PostgreSQL databases. It covers the full spectrum of schema design, from selecting the most efficient data types—such as TIMESTAMPTZ and BIGINT identity columns—to implementing advanced features like Row-Level Security, GIN/GiST indexing, and declarative partitioning. Designed to avoid common pitfalls like silent truncations or unindexed foreign keys, this skill ensures your database is optimized for both transactional integrity and high-concurrency performance, making it ideal for everything from game backends to enterprise-grade APIs.
