+ <function>to_timestamp</function> and <function>to_date</function>
+ exist to handle input formats that cannot be converted by
+ simple casting. These functions interpret input liberally,
+ with minimal error checking. While they produce valid output,
+ the conversion can yield unexpected results. For example,
+ input to these functions is not restricted by normal ranges,
+ thus <literal>to_date('20096040','YYYYMMDD')</literal> returns
+ <literal>2014年01月17日</literal> rather than causing an error.
+ Casting does not have this behavior.
