   @zchovan thank you for the benchmarks! 
   Last thing, to be on a safe side, could you please record INSERTS only if 
min_history is not available + use old logic for writeId removal based on 
min_history if available. @pvary, what do you think?
   ````
   if (!useMinHistoryLevel && isInsert(stmt, txnid)) {
   ....
   }
   ````
