Worked on stabilizing the duckdb-go Go bindings by addressing critical issues related to pointer handling and data binding, with a focus on improving runtime reliability for production workloads. Using Go and database testing skills, resolved panics caused by nil pointer values in nullable UUID columns by implementing reflection-based binding of nil pointers as NULL. Also corrected the insertion logic for custom type pointers by refining internal value checks, ensuring accurate data handling. Expanded test coverage to verify both binding and insertion paths, which reduced the risk of regressions and improved data integrity for UUID and pointer-based values in the duckdb-go repository.
