Tool-kit for JSONb key-number objects

	/**
	* object_summable and "Merge sum" functions are for JSONb key-number objects,
	* most usually key-integer for counting, like json-bags.

	* Change the core of jsonb_merge_sum(jsonb,jsonb) to the correct datatype.
	* The JSON "number" is equivalent to the SQL's ::numeric.
	* Any invalid or empty JSONb object will be represented as SQL NULL.
