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!

Steve
