Json:- Accepting 'integer' value

Hi Team,

Postgres Version:- 12.7
Issue:- JSON data type column accepting 'integer' value
Priority:-Minor

Below is the table definition and insert statement, which is working in
Postgres however it doesn't work in oracle with check constraint(jj is JSON
strict).

postgres=# \d kp
Table "public.kp"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+--------------------------------
id | integer | | not null | nextval('kp_id_seq'::regclass)
jj | json | | |

postgres=# insert into kp(jj) values('98');
INSERT 0 1

But while we checking the same thing in Oracle it doesn't accept this. Is
it an issue with Postgres data type?
