Worked on the EnterpriseDB/cloudnative-pg repository to enhance plugin connectivity reliability in proxy-based environments. Focused on backend development using Go and Kubernetes, the work addressed a bug by updating the plugin connection logic to resolve addresses using fully qualified domain names rather than short service names. This change improved compatibility with cluster-level proxies that inject environment variables, reducing the risk of connection failures and manual workarounds. Test coverage was expanded to validate the new FQDN-based resolution, minimizing regression risk. The result was a more maintainable and robust deployment process for enterprise users operating behind complex proxy configurations.
