CSV is difficult to parse and I am not sure postgres can hadle it.
Use delimited formats, best of all tab-delimited -- your access97
does that, too.

in psql:

test=> \h copy
Command: copy
Description: copy data to and from a table
Syntax:
        COPY [BINARY] class_name [WITH OIDS]
        TO|FROM filename|STDIN|STDOUT [USING DELIMITERS 'delim'];

filename here is an absolute path in the backend's scope


Another option would be:

test=> \?      
 ....
 \copy table {from | to} <fname>
 ....

Here, <fname> should be in the path of your client. This requires the
file to be tab-delimited, while the backend copy allows you to use
other delimiters (not CSV, though). Be aware that if you use the
client copy (\copy), your data will go over the network.
