Worked on the artsy/horizon repository to deliver PostgreSQL 14 compatibility by updating the setup script, ensuring the pg gem correctly identifies the installation path for the new database version. This change streamlined environment configuration, reducing setup issues and improving reliability for both local development and CI pipelines. The approach involved shell scripting for automation, integration with Ruby tooling, and a focus on database management best practices. By targeting PostgreSQL 14, the work enabled smoother onboarding for developers and prepared the project for future deployments. No major bugs were addressed during this period, with efforts concentrated on feature delivery and environment stability.
