Apparently I'm not alone in that, either; a paper by Hellerstein, Stonebraker, and Hamilton[1] has this in section 7.2 (Memory Allocator): "The interested reader may want to browse the open-source PostgreSQL code. This utilizes a fairly sophisticated memory allocator." I think the problem here is that we don't extend that sophistication to shared memory. -Kevin
