PROFILE
Gábor Trexler
During February 2026, Greg Trexler focused on security policy hardening within the hortonworks/cloudbreak-images repository, addressing SELinux denials encountered during PostgreSQL upgrade flows. He implemented a targeted SELinux policy fix by updating policy files and introducing new labeling rules for PostgreSQL directories and binaries, ensuring upgrade operations could proceed securely and without interruption. Using SELinux Policy language and leveraging skills in system administration and security management, Greg validated upgrade workflows under strict SELinux constraints. This work established a stronger, more auditable security baseline, reducing manual intervention and supporting reliable, compliant PostgreSQL upgrades across diverse deployment environments. Depth of work was focused and impactful.
