• Fix to sort startup packet's parameters sent by client. ( bug 444 )(Takuma Hoshiai)

  If order of startup packet's parameters differ between cached connection pools and connection request, didn't use connection pool ,and created new connection pool.

• Fix segmentation fault occurs when a certain Bind message is sent in native replication mode. ( bug 443 )(Bo Peng)

  If the number of parameter format codes is specified to one, but the number of the original query's parameter is zero, bind_rewrite_timestamp() will call memcpy with a negative value. This causes segmentation fault.
