Description
Hey everyone, a few months ago, after recovering from a Clade-generated bug, I was thinking to myself “wouldn’t it be nice if prod DB writes were easy to roll back”. I’ve put something together: it’s a two-container deploy plus a CLI tool. It’s far from being production ready, so please be gentle. All feedback welcome!The nitty gritty: https://eterdb.com/techGitHub: https://github.com/eterdb/eterdb

Could you build this?
No Forking PostgreSQL 18 to implement transaction-level undo, read-dependency tracking, and granular time-travel write recovery requires deep database internals and C engine expertise.
What it would actually take: Requires modifying PostgreSQL core source code (in C) to alter the WAL (Write-Ahead Log), tuple visibility routines (MVCC/vacuuming), and implementing transaction dependency graphs by intercepting read/write locks. The system must reconstruct row histories, compute cascading dependencies across foreign keys and read sets, and handle schema changes without full-database replay. This requires world-class database systems engineers and distributed systems researchers.
