Description:
------------
Using php 5.3.5 with pdo_pgsql and pgsql 9.0.2 when inserting serialized objects 
that contain private variables the serialized string is truncate as soon as it 
hits the private variable.

Objects that do not contain private variables work fine.

When using the pdo_mysql driver it also works fine.

Test script:
---------------
<?php
class foo{
private $_var;
}
$foo=serialize(new foo());
$q=new PDO("pgsql:host=localhost;dbname=testdb","root","");
$q->exec('CREATE TABLE test (data TEXT)');
$s=$q->prepare("INSERT INTO test VALUES(?)");
$s->bindValue(1,$foo);
$s->execute();
$s=$q->query("SELECT * FROM test");
var_dump($s->fetchAll(PDO::FETCH_ASSOC),$foo);

Expected result:
----------------
array(1) {
  [0]=>
  array(1) {
    ["data"]=>
    string(32) "O:3:"foo":1:{s:9:"foo_var";N;}"
  }
}
string(32) "O:3:"foo":1:{s:9:"foo_var";N;}"


Actual result:
--------------
array(1) {
  [0]=>
  array(1) {
    ["data"]=>
    string(18) "O:3:"foo":1:{s:9:""
  }
}
string(32) "O:3:"foo":1:{s:9:"foo_var";N;}"

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Serialized content of private/protected properties contain \0 inside the 
generated string. This causes truncation, to avoid it you need to change the 
column type to binary and write data as a binary string.
