Carriage return --- you evidently have some Mac- or Windows-style
newlines in your data. My recollection is that 7.1 had a different
convention for representing these in COPY data than the later versions
do. If you want to preserve them exactly as-is you might try doing
the pg_dump from 7.1 with the dump-data-as-INSERTs option. If you'd
rather clean up the data then just manually remove the CRs from the dump
file ...
