following characters <emphasis>must</> be preceded by a backslash if
they appear as part of a column value: backslash itself,

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

is a required part of the signature. (The signature is designed to allow
easy identification of files that have been munged by a non-8-bit-clean
-transfer. This signature will be changed by newline-translation
+transfer. This signature will be changed by end-of-line-translation
filters, dropped zero bytes, dropped high bits, or parity changes.)
