But here it is the typecast to json that throws the error, not the `->` operator. I.e.,
```
SELECT '{not valid json}'::json;
```
throws the same error (on PG 14 – for some reason, your sqlfiddle link doesn't open for me).
But I'm nitpicking. Personally, I have no problem with the somewhat different semantics anyhow. But I thought the issue worth mentioning, in case someone thinks it's a big deal.
