使用concatenate operator ||更新jsonb列,例如:
create table example(id int, js jsonb);
insert into example values
(1, '{"id": "3", "username": "abcdef"}');
update example
set js = js || jsonb_build_object('id', (js->>'id')::int)
returning *;
id | js
----+---------------------------------
1 | {"id": 3, "username": "abcdef"}
(1 row)
