The original query doesn't work 🔴 :

dvdrental=# SELECT
  jsonb_populate_recordset(
    null :: employees,
    json_agg(jsonb_build_object(
      'id', id, 'name', name, 'age', age, 'salary',
      salary
    ))
  ) AS employees
FROM
  employees;

ERROR:  function jsonb_populate_recordset(employees, json) does not exist
LINE 2:   jsonb_populate_recordset(
          ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

Using the suggestion from the hints 🟢 :

dvdrental=# SELECT
  jsonb_populate_recordset(
    null :: employees,
    json_agg(jsonb_build_object(
      'id', id, 'name', name, 'age', age, 'salary',
      salary
    ))::jsonb
  ) AS employees
FROM
  employees;

         employees
