Add all the node-specific json fields.
Any class that needs to add such info should override this function rather than doing it in do_contextualize(). E.g. the parse tree node for AVG() may have "distinct" field to indicate if AVG(DISTINCT ...) is used or not.
json_obj | Json object for this parse tree node. |
Reimplemented from Parse_tree_node_tmpl< Context >.

Call this to record in the WITH clause that we are contextualizing the CTE definition inserted in table reference 'tl'.
