Using lastInsertId with PgSQL just returns the OID which is not what we want.

As all the tables are using sequences I thought I may as well get the currval of their sequence in the primary key field.

Ran these queries through phpPgAdmin and it returns currval row with a value, but through PDO it returns nothing.

I started using a simple PDO::query() call and then moved it into a full prepare/execute call.

Reproduce code:
$sql = "INSERT INTO table (bah, foo) VALUE ('woo', 'waz)";
$statement = $this->db->prepare($sql);
if (!$statement->execute()) {
    throw new Exception("Failed query [$sql] with error [" . $this->db->errorInfo() . "]");

$sql = "SELECT currval('".strtolower($idnr_seq)."')";
$stmt = $this->db->prepare($sql);
if (!$statement->execute()) {
    throw new Exception("Failed query [$sql] with error [" . $this->db->errorInfo() . "]");


Expected result:
Array ( [currval] => '27' )

Actual result:
Array ( [currval] => )

Unsure, but may as well note. I am running PgSQL 8.0.1.

Preparing $stmt and executing $statement is usually not a good apporach :)
