Copy From suggestion

Hello all,
Firstly, I apologise if this is not the correct list for this subject.
Lately, I've been working on a data conversion, importing into Postgres
using Copy From. The text file I'm copying from is produced from an ancient
program and produces either a tab or semi-colon delimited file. One file
contains about 1.8M rows and has a 'comments' column. The exporting program,
which I am forced to use, does not surround this column with quotes and this
column contains cr/lf characters, which I must deal with (and have dealt
with) before I can import the file via Copy. Hence to my suggestion:
I was envisioning a parameter DELIMITER_COUNT which, if one was 100%
confident that all columns are accounted for in the input file, could be
used to alleviate the need to deal with cr/lf's in varchar and text columns.
i.e., if copy loaded a line with fewer delimiters than delimiter_count, the
next line from the text file would be read and the assignment of columns
would continue for the current row/column.
Just curious as to the thoughts out there.
Thanks to all for this excellent product, and a merry Christmas/holiday
period to all.
