We were looking at tooling for snapshotting production data for testing purposes, that use case is interesting to have the diff view based on changes happening from application actions. Would you use it for testing changes or more for debugging production issues?

Well, my main use case would be to speed up project onboarding where I can play around with the app from user perspective and check how my actions impact database... Could help cutting through a lot of frontend/backend layers and just focus on raw data.

If you have multiple DB snapshots and WAL enabled, theoretically you could inspect the log to see what happened inbetween. There's pg_xlogdump for that but I think it will output very raw data...

How would you want to actually look at the database diff? Just a summary view of rows that were changed given a certain time period?
