Eliminating carriage returns?

I've done a dump from postgresql 7.1 via

psql -S admin adminweb > dump.sql

now, I'm trying to import into 7.4

psql adminweb admin < dump.sql

and I'm getting errors about

ERROR:  invalid input syntax for integer: "
or
ERROR:  literal carriage return found in data

is there a compatibility issue between 7.1 and 7.4?
