echo '<pre>';
var_dump($meta);
echo '</pre>';

El resultado del ejemplo sería:
array(3) {
["author"]=>
array(5) {
["num"]=>
int(1)
["type"]=>
string(7) "varchar"
["len"]=>
int(-1)
["not null"]=>
bool(false)
["has default"]=>
bool(false)
}
["year"]=>
array(5) {
["num"]=>
int(2)
["type"]=>
string(4) "int2"
["len"]=>
int(2)
["not null"]=>
bool(false)
["has default"]=>
bool(false)
}
["title"]=>
array(5) {
["num"]=>
int(3)
["type"]=>
string(7) "varchar"
["len"]=>
int(-1)
["not null"]=>
