It is strongly recommended that applications generating COPY data convert
data newlines and carriage returns to the <literal>\n</> and
<literal>\r</> sequences respectively. At present it is
possible to represent a data carriage return without any special quoting,
and to represent a data newline by a backslash and newline. However,
these representations will not be accepted by default in future releases.

Note that the end of each row is marked by a Unix-style newline

desired if given a file containing DOS- or Mac-style newlines.
This is expected to change in future releases.
<command>COPY TO</command> will terminate each row with a Unix-style

("\r\n") on MS Windows. <command>COPY FROM</command> can handle lines
ending with newlines, carriage returns, or carriage return/newlines.
