Node 14.0.0 - pg does not response

Running a postgres locally
```javascript
import { Pool } from 'pg';
const pool = new Pool({})

describe('check connexion', () => {
  it('should select 1', async () => {
    const result = await pg.query('SELECT 1 as hey');
    expect(result.rows[0]).toEqual({ hey: 1 });
  });
  afterAll(() => pg.end());
});
```
Fails with current node 14.0.0
Works on node 12.16.2.
