Incorrect documentation for notice event

[tlhunter]

According to the website documentation the notice event receives a string. However it actually receives an instance of Error with custom properties added:

docs:

client.on('notice', (notice: String) => void) => void

actual:

{
  client.on('notice', (notice) => {
    console.log(notice instanceof Error); // logged below
    assert.equal(notice.name, 'notice');
    assert.equal(notice.message, 'oh no');
    // console.log('client on notice', notice);
    // console.log('keys', Object.keys(notice));
    // console.log('stack', notice.stack);
    assert.ok(!notice._parentObject, 'got parent object in notice');
  });

  client.query("DO language plpgsql $$ BEGIN RAISE NOTICE 'oh no'; END $$;", () => {
  });
}

{ notice: oh no

I do Object.assign({message: notice.message}, notice) to get a regular JavaScript object.
