Description:
------------
Running PHP5.1.0RC1, postgresql 8 server with v7.4.7 client libs (pretty sure native prepared statements are disabled).

When trying to execute this query:
$stmt = $db->prepare("SELECT ('0' || :param || '0')");
$stmt->execute(array(':param' => 123));

PDO actually executes this SQL statement: SELECT ('0' || :param || '0'), without replacing :param.

It seems like the parser thinks the whole "0' || :param || '0" part is quoted, though its not.

The query "SELECT (0 || :param || 0)" works as expected.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

This works for me in current PHP_5_1 branch using SQLite.

Problem still exists with php5-200509020830, pgsql driver. 

Did not test with any other driver.

Sounds like a greedy regex in our query parser.
