Subject: [PATCH] Fix bad query execution plan when executing
SQL{Dict,Queue}_validateMessageList.
serialization_tag is checked for equality, but processing_node is checked for inequality.
So the right index column order is serialization_tag then processing_node.
serialization_tag is not used in a where-expression in any other zsqlmethod, so previous index can be removed to save space and insertion speed.
