Hi, We are developing a solution which will run in thousands of small cash till machines running Linux and we would like to use PostgreSQL but there is a insecurity feeling regarding the solution basically because these boxes would be exposed to an insecure environment and insecure procedures like: non controlled power outages, untrusted hardware, no appropriate environment for hardware (dusty, hot) etc...
Our major concern is related to the write-back issues we can face in this environment. Is there a way to prevent it or a way PG can be configured to detect write-back configurations? Don't think so, but... Basically, the question is: is there a way to guaranty a reliable PG database in an untrusted and insecure environment? Maybe some kind of file system could give this guaranty, not sure.. -- Reimer <carlos.rei...@opendb.com.br>
