PostCENN: PostgreSQL with Machine Learning Models for Cardinality Estimation
Summary: PostCENN inserts ML models as first-class PostgreSQL citizens to enhance cardinality estimation. An end-to-end lifecycle trains, deploys in the optimizer, and deletes models, blending ML with histograms for targeted schema portions. (summarized by gpt-5-nano on Feb 09 2026)
