The update is on the page that vacuum was just removed. Before we try to understand/attack the bug exactly, first I'd like to see the complete xlog output. Your xlog output is imcomplete -- for example, the first line after "b" should be "lk %u", the second line after "ti" should be "d %u%u". Can you check out why the output looks like that? If you want to examine the source code, look at heapam.c/heap_desc(). Regards, Qingqing
