It is like the problem due to the confliction of vacuum & update. 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().
