Please, don't flame me for this now : Could PostgreSQL be working in two modes : development (SET DEVELOPMENT MODE) and production (SET PRODUCTION MODE). 1) In development mode, each object has an md5 signature showing whether the object is updated or not. If the object has changed, it is reloaded. This would work even in a cluster. Object modification and deletion would only be allowed in development mode. 2) In production, object deletion and modification would not be possible. No need for md5 signatures then. Switching from production <-> development would only be possible after all transactions have ended. Pretty stupid, I agree, but this would make life easier. Just my 0,00002 cents. Cheers, Jean-Michel
