3.12 automatic update got stuck – how can I verify DB tables upgraded?

Hi – What’s the easiest way to verify that the database update step in WP 3.12 automatic update in fact succeeded, or to simply repeat it or re-install to be sure?

I use self-hosted WordPress and just did an automatic update from 3.11 to 3.12. The update process got as far as “Installing updated files …” and then got stuck there.

After several minutes, I realized that I’d accidentally left myself logged in at my PHP vadmin console after backing up the database. (My bad!) Presumably, this locked the database against writes and caused the WordPress automatic update to get stuck. I logged out of PHPadmin, but the WordPress autoupdate screen showed no change. I never saw the “Updating database …” or “Installation successful messages.”

I hit reload, but it asked me “Are you sure you want to do this?” so I didn’t continue.

WordPress admin screen claims that it’s been updated to 3.12 and the site seems to be fine, but I’m not sure the database portion of the install actually succeeded.

1) How can I verify that the database portion of the install (and the rest of it, for that matter) truly succeeded?
2) Should I just do an “automatic reinstall” of 3.12 to be safe?

I have backups of both the site files and the DB before and after the 3.12 update attempt, so if all else fails, I can always restore from backup. Thanks for any advice!

P.S. I did the 3.12 automatic update on another WP site I have *without* PHPadmin logged in, and it ran just fine *and* displayed the “Updating database …” and “Installation successful!” messages.
