importing in sql

Hi, I am trying to import loads of data into postgres, I am  having
trouble with a field which is a sequence. I know how to import data
using a delimiter with the copy command. But I need to know how I
increase the sequence on each line of import.

My Table has the following format.

field1    serial primary key,
field2    char (50),
field3    char(50),
field4    int,
field5    date

The file has the following format

field2|field3|field4|field5|

Each field is separated by a | (pipe), How do I insert the sequence
number before field2? I have like 30 files in this format and I need to
import them in one table with each line having unique number.  Has
anyone come across similar situation? any help would be greatly
appreciated.

Please let me know if you need more info.

Thanks in advance.
