Re: remaining sql/json patches

Hello,

I'm not sure I've chosen the most appropriate thread for reporting the
issue, but maybe you would like to look at code comments related to
SQL/JSON constructors:

  * Transform JSON_ARRAY() constructor.
  *
  * JSON_ARRAY() is transformed into json[b]_build_array[_ext]() call
  * depending on the output JSON format. The first argument of
  * json[b]_build_array_ext() is absent_on_null.


  * Transform JSON_OBJECT() constructor.
  *
  * JSON_OBJECT() is transformed into json[b]_build_object[_ext]() call
  * depending on the output JSON format. The first two arguments of
  * json[b]_build_object_ext() are absent_on_null and check_unique.

But the referenced functions were removed at [1]; Nikita Glukhov wrote:

(That thread seems too old for the current discussion.)

Also, a comment above transformJsonObjectAgg() references
json[b]_objectagg[_unique][_strict](key, value), but I could find
json_objectagg() only.
