Kepler: Robust Learning for Faster Parametric Query Optimization

Summary: Kepler: end-to-end learning-based parametric query optimization that bypasses unreliable cost models. Row Count Evolution perturbs sub-plans; candidates are evaluated by actual executions, and uncertainty-aware ML predicts the fastest plan for PostgreSQL speedups.
