The query callback can only be called once (and if it weren’t, we wouldn’t want to silently ignore that):

Suggested change
var calledDone = false
client.query(new pg.Query({ text: 'SELECT $1::timestamp', values: [new Date(undefined)] }), function (err, res) {
if (!calledDone) {
calledDone = true
assert.equal(err.message, 'Query parameter value cannot be an invalid date.')
client.end(done)
}
})
client.query(new pg.Query({ text: 'SELECT $1::timestamp', values: [new Date(undefined)] }), function (err, res) {
assert.equal(err.message, 'Query parameter value cannot be an invalid date.')
client.end(done)
})

It will cause this error, as the connection also gets terminated, and the callback will be executed again.

Message: 'Connection terminated' == 'Query parameter value cannot be an invalid date.'
AssertionError [ERR_ASSERTION]: 'Connection terminated' == 'Query parameter value cannot be an invalid date.

That’s a serious bug, then.
