Breaking Change Analysis

Result: No breaking changes detected

Reasoning: This PR is purely additive - it adds support for the PostgreSQL "timestamp with time zone" format string by mapping it to Types.date_time. No existing behavior is modified. Previously unrecognized format strings would fall back to a default type; now this specific format is recognized and correctly typed. This is a feature enhancement that improves code generation for users with PostgreSQL-style schemas, without affecting any existing users or requiring any changes to their workflows.
