I don't know the history but psqlodbc driver seems
to have been unchanged about this point since long.
Probably someone wanted this conversion long ago
for e.g. editing sentences with new lines and it's
pretty useful for Windows' users.
However it doesn't seem preferable for *nix clients
which don't need \r(Carriage Return)s for new lines.
I have seen the request to add an option to enable
/disable new lines conversion only once pretty long
ago.
