JSON Serializer VS Postgres jsonb_agg

[mmmcorpsvit]

Postgres have native JSON serializer, why DRF not use so powerful feature ?

example query

SELECT
            jsonb_agg(s.*) example
        FROM
            (select
                id,
                cam_id,
                address,
                lat,
                long,
                status

              FROM cars_cams
              order by name ) as s;

my little tests:
table with 3000 records

use native serializer:
0:00:02.620534

use postgres json serialier:
0:00:00.098092

around x250 speedup!
