In the original data record in Sybase there is a column containing, i.e.
some UNIX print command to be read and executed by the application:

    cmd | lpr ...

it is exported into the file as

    cmd \| lpr ...

because the export delimiter is set to '|';

the COPY in text mode was complaining because it interpreted the |
of the sequence \| as an delimiter and the number of columns did not
matched.

I will provide tomorrow the exact input line, the exact COPY command and
the error.
