ignoring primary key violations in COPY command

Hi all,

We are importing the data from the CSV file into the database using COPY
command. But when the 'primary key ' violation occurs , it stops

Then and there and data is not updated into the tables. Also in the CSV
file the number of columns is not fixed , its varies

In number , it can range anywhere between 1 -22, I need to figure out a
way such that I need to update only those columns which are present

In the CSV file . This of course I would like to accomplish using COPY
command , Please let me know if at all this is possible in postgresql
8.1

Thanks and regards,

Rajendra Singh
