Postgres Build 2021

Why talking about old things like ACID properties? We all know everything we
need to know about that, right ? Well, I found out that even though this
properties were old, well known and beautifully documented, it didn't mean
people actually understood them. I found myself repeatedly explaining how it
works, what tradeoffs
were made and why.

Particularly, transaction isolation and its anomalies were not commonly known
and I found out developers adding extra layers in their application instead of
simply adjusting their database isolation level for that particular query.
