    $connection = yield Postgres\connect('host=localhost user=postgres dbname=test');

    /** @var \Amp\Postgres\Statement $statement */
    $statement = yield $connection->prepare('SELECT * FROM test WHERE id=$1');

    /** @var \Amp\Postgres\TupleResult $result */
    $result = yield $statement->execute(1337);

    while (yield $result->advance()) {
        $row = $result->getCurrent();
        // $row is an array (map) of column values. e.g.: $row['column_name']
    }
});
