Worked on updating the installation documentation for the jumpserver/docs repository to require PostgreSQL 16, replacing the previous 9.6 version. Focused on ensuring that deployment processes align with current database management standards and that onboarding is streamlined for new users. Used Markdown to deliver clear, traceable documentation changes, linking updates directly to the relevant commit for full auditability. Emphasized documentation hygiene and cross-version support, reducing potential installation errors and support issues. The work demonstrated attention to detail in aligning prerequisites with the evolving ecosystem, leveraging skills in database management and technical documentation to improve reliability and maintainability for future deployments.
