Bug Error With Page Not Found * warning: pg_query() [function.pg-query]: Query failed: ERROR:

I recently switched over to pathauto for manual creating aliases and am in the process of re-indexing the site. When a Page Not Found error occurs from a page that used to have a different URL.

This error appears when a user uses a GSA or google to search a page and the old URL appears and when they hit the hyperlink this appears:

Page not found

The requested page could not be found.
___________________________________________

This error is reproducible any time a user attempts to hit a page that had a valid URL path before but has been renamed and not yet re-indexed.

For instance if you search on google, or on my site (www.icts.uiowa.edu) for BodPod FAQ and select (from google) the link that says:
BOD POD® | Institute for Clinical and Translational Science the error will occur.

I would have expect just the usual "Page Not Found" Message with out the long error string. Which is very confusing to users and renders in a large block of text on the page.

If a user attempts to find a page that simply does not exists, this error does not occur.
It always occurs in the situation described above.

I had noticed this error twice prior deploying pathauto but could not reproduce it and trace it to anything, now because of all of the pages Aliases being rewritten I was able to narrow this issue down.
