I have a doubt regarding the time of dump / check WAL buffers when serializing isolation in Postgres. Is it possible to lose recognized writes even if the transaction executes at the serialization isolation level? What happens if the transaction has been validated in the WAL buffer and the machine subsequently hangs without the possibility of recovery? Does Postgres still validate serialization isolation transactions on disk?
