Importing data from csv

Hi Folks,

sorry if this is a duplicate post, i've been tryin to find a solution of
importing data into postgres from a csv file. The problem is, I have a
database which consists of columns which contain newline characters (mac and
unix). now when i export these files to a csv format, there are some line
breaks (mixed unix and mac) in the data which breaks the copy procedure.

I also tried using the script posted in one of the previous posts..

#! /usr/bin/perl
$inquotes = 0;
while (<>){
# Chop the crlf
chop ($_);
chop ($_);

# this first bit goes through and replaces
# all the commas that re not in quotes with tildes
for ($i=0 ; $i < length($_) ; $i++){
$char=substr($_,$i,1);
if ($char eq '"' ){
$inquotes = not($inquotes);
}else{
if ( (!$inquotes) && ($char eq ",") ){
substr($_,$i,1)="~";
}
}
}
# this replaces any quotes
s/"//g;
print "$_\n";
}

cat data_file | perl scriptname.pl > outputfile.dat

and when i run the copy command i get messages like data missing for xyz
column.
any possible hints.......
