I have no relation to the project, but calling this problem solved and then offering a vastly inferior solution to the proposal (PITR) is a bit unfair

Point one remains. The "solution" appears to come from somebody who thinks its OK to run Claude against a production database.... “wouldn’t it be nice if prod DB writes were easy to roll back”

The point remains that if they ran Claude against a test database they would have found the bug without killing their production database, and therefore also not need to come up with an over-engineered "solution".

Sometimes also the less over-engineered the better. Stuff like PITR and pg_dump is battle-tested and easy to reason about.
