WordPress 2.3 database error

I updated my blog to WordPress 2.3 last night and noticed this morning that visitors who posted comments were getting an error. Their comments were posting but included the following error:

WordPress database error: [Table ‘wordpress.wp_post2cat’ doesn’t exist

It included some other strings as well but the database part was consistent. I looked around till I found this thread at the WordPress discussion forums that mentioned the problem might be an incompatible plugin like Google Sitemap. I was using an older version and decided to deactivate it and that fixed the error. Google Sitemap plugin has now been updated to work on WordPress 2.3.

This brings up a possible feature request. It would be great if WordPress would automatically disable any out-of-date plugins automatically.

Otherwise version 2.3 is working fine.
