Over a two-month period, 10328485@zte.com.cn developed and enhanced security-focused audit logging features for the ApsaraDB/PolarDB-for-PostgreSQL repository. They built the Plaudit PostgreSQL Audit Logging Extension, establishing a configurable auditing framework using C, Makefile, and SQL, with GUC-based configuration and event hooks to tailor audit scope and logging behavior. In subsequent work, they improved the polar_audit module by adding password redaction and robust CSV formatting, introducing helpers for safe data handling and enhancing event classification. Their contributions deepened the database’s compliance and security capabilities, demonstrating strong skills in C programming, database auditing, and PostgreSQL extension development.
