What version of PostgreSQL is this skill optimized for?

This skill is specifically designed for PostgreSQL 16 and above, utilizing modern features like Identity columns and advanced JSONB handling.

Why does it recommend BIGINT over SERIAL?

Modern PostgreSQL standards prefer GENERATED ALWAYS AS IDENTITY (BIGINT) because it is SQL-standard compliant and handles sequence ownership more cleanly than the legacy SERIAL type.

Does it support data integrity checks?

Yes, it provides patterns for Foreign Keys, Check constraints, and Unique constraints to ensure your data remains consistent at the database level.

Can this skill help with naming conventions?

Absolutely. It includes validation rules to ensure table and column names follow lowercase, snake_case standards for maximum compatibility and readability.
