Why did I do that?

Gallery 2.3 just came out, and I made the mistake of upgrading instead of waiting for it to shake out a bit. And of course, things are slightly broken. Everything works, but at the end of every page is this:

Database Error
An error has occurred while interacting with the database.

The exact nature of database errors is not captured unless Gallery debug mode is enabled in config.php. Before seeking support for this error please enable buffered debug output and retry the operation. Look near the bottom of the lengthy debug output to find error details.

The weird thing is that it was happening almost everywhere, and now it’s only some pages.
