PostgreSQL’s MVCC and other databases: why the approach is flawed

The author critiques PostgreSQL’s implementation of MVCC. He claims the design introduces performance and complexity issues. Similar multi‑version schemes in other databases are examined. The post argues that these systems share the same fundamental problems. Examples illustrate hidden costs in transaction handling. The author suggests alternative concurrency models. He invites readers to reconsider reliance on MVCC for new projects. The full argument is available on the BoringSQL blog.
