Use the aggregated positions and ages from ARRAY_AGG as input to ARRAY_TO_JSON to obtain a JSON object.
The example uses the table(s) created earlier.
SELECT pos, ARRAY_TO_JSON(ARRAY_AGG(age ORDER BY empId, NEW intarr5()))
FROM employeeTable 
GROUP BY pos
ORDER BY pos;
Result:
pos         ARRAY_TO_JSON(ARRAY_AGG(…))
