AFAIK it is not. As Tom once explained me, it is ok for tuples xmax to be !=0 and still have a valid tuple. The validity is determined by some bits in tuple header. But I think the most useful behaviour should be to dump system fields too, so mildly knowledgeable sysadmin can import the dump and do the right thing afterwards (like restore data as it was before transaction nr 7000) ------------- Hannu ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
