   This commit changes the order of operations from:
   COPY to temp_metric1
   INSERT from temp_metric_1 to metric_1 ON CONFLICT DO NOTHING
   COPY to temp_metric2
   INSERT from temp_metric_2 to metric_2 ON CONFLICT DO NOTHING
   
   to
   
   COPY to temp_metric1
   COPY to temp_metric2
   INSERT from temp_metric_1 to metric_1 ON CONFLICT DO NOTHING
   INSERT from temp_metric_2 to metric_2 ON CONFLICT DO NOTHING
   
   By combining the inserts together at the end of the transaction
   it decreases the times that locks on conflicting rows are held.
