Could you COPY into one table then insert from that to your target table? Well, there are some issues. First your client needs to support it. E.g. psycopg2 supports only some specific CSV formatting in it's methods. (plus I had sometimes random psycopg2 crashes, but guarding against these is cheap compared to the speedup from COPY versus INSERT) Plus you need to be sure that your data will apply cleanly (which in my app was not the case), or you need to code a fallback that localizes the row that doesn't work. And the worst thing is, that it ignores RULES on the tables, which sucks if you use them ;) (e.g. table partitioning). Andreas
