Worked on stabilizing the PostgreSQL adapter within the prisma/prisma repository, focusing on improving resource management during transactional workflows. Addressed a memory leak by ensuring error event listeners were properly detached when transactions were either committed or rolled back, introducing a dedicated cleanup function to manage listener removal. This solution mitigated the MaxListenersExceededWarning and reduced memory growth under high-concurrency scenarios, resulting in more reliable database interactions for Prisma users. The work leveraged JavaScript and TypeScript, with an emphasis on error handling and memory management, and contributed to the overall stability and efficiency of the PostgreSQL integration in Node.js environments.
