Обсуждение: BUG #14080: JSONB order changes when using json_pretty()

The following bug has been logged on the website:

Bug reference:      14080
Logged by:          Jack
Email address:      jack@fastly.com
PostgreSQL version: 9.5.2
Operating system:   Mac OSX
Description:

while looking though datasets I noticed json_pretty is retuning a different
record.

This query will return an id that I expect and other defendant queries seem
to work
```
select jsonb_array_elements(details->'version'->'domains'), id from services
order by id limit 1 offset 400;
```

This query returns a random record both the id and the json are valid they
are just the wrong one.

```
select jsonb_pretty(details->'version'->'domains'), id from services order
by id limit 1 offset 400;
```

=E2=80=8BYour subject line and message do not seem to match each other.

WRT the subject line, jsonb documentation states:

> =E2=80=8Bjsonb does not preserve white space, does not preserve the order=
 of
object keys, and does not keep duplicate object keys.

So there isn't a bug there.

Without a self-contained example for the message body I'm inclined to
suspect user-error/mis-understanding.  Please provide something that
someone else can run to see the misbehavior.
