In a 32-bit machine low memory is the first physical GB or so, and high memory is the rest, and there are certain things that have to be in low memory because the hardware won't cope otherwise. Thus, you can run out of lowmem even when there's scads of free memory in highmem. If you've got more than about a GB of physical RAM you need to be running a 64-bit kernel; otherwise you're wasting your hardware. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
