These things look like bugs to me:

heap_xlog_clean doesn't update the page's LSN and SUI.

heap_xlog_insert and heap_xlog_update leave random bits in the
inserted/updated tuple's t_ctid.  heap_xlog_update leaves random
bits in the updated tuple's t_cmax in the "move" case.

I am not sure about what sort of visible fault these omissions could
produce; perhaps none.  But they look like dangerous things IMHO.
