Dereferencing PG_Result

Here's the code:

#!/usr/bin/perl

use Pg

$conn = Pg::connectdb("dbname = mydb");
$result = $conn->exec("select * from mytable");

print $result "\n";

----end code---

This is what's returned:

PG_results=SCALAR(0x8110e14)

----end result-----
Mydb has a table mytable with a field myfield.  There are two tuples.

Question:  How can I deference the pointer to get at the actual data?
