I don't see any problem in removing this extra parameter.

However another thought, can it be used to report a bit meaningful
error for field size < 0 check?

if (fld_size < 0)
        ereport(ERROR,
                (errcode(ERRCODE_BAD_COPY_FILE_FORMAT),
                 errmsg("invalid field size for column %d", column_no)));
