Substring might do it for you.
won't doing it in SQL still result in a BYTEA result which will be wrapped when dumped via COPY ?
instead, I think this needs to be done externally to sql, like by piping the resulting file through something like ...
tail -c +25 infile.dat | head -c -2 > outfile.dat
or doing something in perl or whatever.
