As I said, to get rid of the superflous ".data->>" everywhere. Take this query for example: SELECT cities.data ->> '$.name' AS city_name, countries.data ->> '$.name' AS country_name FROM cities JOIN countries ON cities.data -> '$.country_id' = countries.data -> '$.id'; It could be much smaller if the DB knew that all my tables are of the "single data column with JSON" form.
