The percentiles aggregation computes the values below which a given percentage of the data falls.
In this example, the aggregation will return the 50th and 95th percentiles for `rating`.

```sql
SELECT pdb.agg('{"percentiles": {"field": "rating", "percents": [50, 95]}}') FROM mock_items
WHERE id @@@ pdb.all();
```

```ini Expected Response
                                 agg
---------------------------------------------------------------------
 {"values": {"50.0": 4.014835333028612, "95.0": 5.0028295751107414}}
(1 row)
```
