* call-seq:
* conn.on_notice {|message| ... }
*
* Notice and warning messages generated by the server are not returned
* by the query execution functions, since they do not imply failure of
* the query. Instead they are passed to a notice handling function, and
* execution continues normally after the handler returns. The default
* notice handling function prints the message on <tt>stderr</tt>, but the
* application can override this behavior by supplying its own handling
* function.
