It sounds ideal but I remember that Vadim said inserting a 2GB record is not good idea since it will be written into the log too. If it's a necessary limitation from the point of view of WAL, we have to accept it, I think. BTW, I still don't have enough time to run the huge sort tests on 6.5.x. Probably I would have chance next week to do that... --- Tatsuo Ishii
