Hint bit updates are not WAL-logged. I dont know if it would be seen as a "half baked feature".. or similar, and I dont know if the hint bit problem is solvable at all, but I could easily imagine checksumming just "skipping" the hit bit entirely. It would still provide checksumming for the majority of the "data" sitting underneath the system, and would still be extremely usefull in my eyes. Jesper -- Jesper
