Logged by: Uri Parush
Email address: urip@ensilo.com

Description:

Hi, I think I found a bug in PostgreSQL json column type.
I created the next table:
CREATE TABLE public."Dummy"
(
json json
)

And insert the next data:
INSERT INTO public."Dummy"(
json)
VALUES (
'{ "ID": 9059650307334996772}'
);

The data that was saved was incorrect:
{"ID":9059650307334997000}

Looks like PostgreSQL round the number in the insertion.

Doesn't work that way for me -- mine returns the original number. In
particular, the json datatype doesn't do any parsing at all, so it "cannot
happen". jsonb does parsing, but that one also doesn't round it off.

Are you doing this from psql or some other frontend tool? My guess is the
frontend tool is somehow messing with the data for you. If you didn't
already do it in psql, please confirm if you can reproduce it from there.

I’m using pgAdmin.

I will check it without it now

I can reproduce this bug, at least with pgadmin4 2.1 (View Data -> All
rows).

You should take a look there to see if it has been already reported:
