copied!<p>To quote from the <a href="http://www.postgresql.org/docs/8.3/interactive/sql-copy.html" rel="nofollow">documentation</a>:</p> <blockquote> <p>It is strongly recommended that applications generating COPY data convert data newlines and carriage returns to the \n and \r sequences respectively. At present it is possible to represent a data carriage return by a backslash and carriage return, and to represent a data newline by a backslash and newline.</p> </blockquote> <p>So I would say the following will work:</p> <pre><code>npgsqlCopySerializer.AddString("another\\\r\\\naddress"); </code></pre> <p><strong>EDIT</strong>: I tried it for myself and there seems to be a bug in <code>NpgsqlCopySerializer.AddString()</code>:</p> <pre><code>if (escapeAt > bufferedUpto) { int encodedLength = ENCODING_UTF8.GetByteCount(fieldValue.ToCharArray(bufferedUpto, escapeAt)); MakeRoomForBytes(encodedLength); _sendBufferAt += ENCODING_UTF8.GetBytes(fieldValue, bufferedUpto, escapeAt, _sendBuffer, _sendBufferAt); bufferedUpto = escapeAt; } </code></pre> <p>The second line throws the <code>ArgumentOutOfRangeException</code> after the two escape sequences (<code>\r</code> and <code>\n</code>) are processed and added to the output buffer, since at that moment <code>bufferedUpto == 9</code> and <code>escapeAt == "another\r\naddress".Length == 16</code></p> <p>Now I even found <a href="http://pgfoundry.org/tracker/index.php?func=detail&aid=1011215&group_id=1000140&atid=590" rel="nofollow">this bug</a> reported at the Npgsql tracker.</p>
