Error: PDOException: SQLSTATE[22P02] & Exception: SQLSTATE[42703]

I'm getting the following errors on a fresh install of Drupal 7 Alpha2, Views 7--3. I have enabled the tracker view and created a basic article page. I'm running on PostgreSQL 8.4, and XAMPP 1.6.8; Apache 2.2.9, PHP 5.2.6.

It doesn't look like the query's placeholders are being replaced with the array of arguments.

I'm getting this error at: example.com/tracker

The live preview of these views throw the same errors.

Let me know if I you need any more details.
