Worked on updating the PostGIS installation documentation for RHEL 9 within the EnterpriseDB/docs repository, focusing on aligning the installation process with recent changes in dependency management. The update removed the requirement for the EPEL repository, reflecting that all necessary dependencies are now provided directly through EDB repositories. This change streamlined the installation flow for RHEL 9 users, reducing potential setup friction and improving documentation accuracy. The work involved technical writing in Markdown, leveraging Linux and PostGIS expertise, and collaborating across teams to ensure policy alignment. No major bugs were addressed during this period, with efforts concentrated on documentation enhancement.
