Worked on the greenbone/gvmd repository to enhance upgrade reliability by refining the pg-gvm extension’s version check. Addressed a bug where unnecessary upgrades were triggered by updating the logic to only initiate upgrades if the installed pg-gvm version was older than 1.1, rather than simply not equal to 1.1. This adjustment reduced deployment risk and improved stability across environments by ensuring upgrades occurred only when needed. The solution was implemented in C, leveraging database management skills to align upgrade behavior with version semantics. Commit messages and issue references were improved to provide clearer traceability and support future maintenance efforts.
