anonymous rows in Node 6

Any idea why starting from Node.js 6 we are getting data rows with anonymous in front?

I mean, the Result object looks like this in the console:

{ command: 'SELECT',
  rowCount: 1,
  oid: NaN,
  rows: [ anonymous { id: 1, login: 'user-1', active: true } ]

And if we print a single row:

console.log(result.rows[0]);
//=>
// anonymous { id: 1, login: 'user-1', active: true }

What is that anonymous thing and why is it there?

It seems to me that it is no actual change, only in console.log. Try using console.log(JSON.stringify(result)). It does not change the effect of any code.

This does not affect only console logs. I am using assert.deepStrictEqual to compare resultsets returned from database to some expected datasets, and after switching to postgres started getting failing asserts when comparing [ anonymous { count: '0' } ] to [{ count: '0' } ]

resultset.map(row => Object.assign({}, row)) fixes failing assert for me.
