Hello again,  
Unfortunately we doesn’t support array of json in postgresql.  
But you can use the [addField](https://docs.forestadmin.com/developer-guide-agents-nodejs/agent-customization/fields/computed) customization to display it as a JSON in readOnly !

```javascript
.addField('myJsonColumn', {
      columnType: 'Json',
      dependencies: ['myArray'],
      getValues: records => {
        return records.map(r => {
          return r.myArray.map((a) => {
            return JSON.stringify(a);
          });
        });
      },
    });

```

Let me know if my proposal can help you 🙏
