Hi, I think I had the exact same problem as you do a while back and I solved it by removing the header row and the "CSV HEADER" clause of the statement. For the large files I had, it was easier (for me) to remove the header row than it was to escape out all the quotes (or regen the file): COPY deal_lines_temp_load FROM 'c:/temp/autodrs_deal_lines.txt' WITH DELIMITER AS '^'; I think the parser doesn't look for nor generate quoted rows except when CSV is specified.. It would be nice if there was a way to specify a "HEADER" row without invoking CSV parsing rules (friendly hint to core devs!) :) Let us all know if that works!
