how to remove a item from json column use postgresql

Question

version = 9.5.5

Now I have a column named info, like this:

[{"id":1, "name":"car"},{"id":2, "name":"bus"}]

I want to remove {"id":2, "name":"bus"} which id = 2, instead of info::jsonb - 1,not by index but the key-value, so how can I do that? thanks

select jsonb_agg(e.value) from (
    select '[{"id":1, "name":"car"},{"id":2, "name":"bus"}]'::jsonb as data
) a, jsonb_array_elements(a.data) e
where e.value->>'id' <> '2'
