Worked on the hectorqin/hyperf repository to improve PostgreSQL compatibility in the model generation workflow. Addressed a bug that caused the gen:model command to fail when targeting PostgreSQL databases, focusing on enhancing the PostgresGrammar component to accurately list column metadata and support table comments. Leveraged PHP and SQL skills to refine schema management, ensuring that model generation now reliably reflects PostgreSQL-specific structures. These changes reduced the need for manual adjustments and streamlined onboarding for projects using PostgreSQL. The work demonstrated a methodical approach to CLI tool enhancement, emphasizing database compatibility and maintainability within the code generation process.
