  1. Speed up table_exists? for databases with a large number of tables 

    At New Relic, we have hundreds of thousands of tables, and our migrations took 30 minutes without this similar patch. This cuts it down to a more reasonable amount of time.

The rescue false part is ugly, but necessary as far as I can tell. I don't know of a cross-database statement you can make that will work without trapping errors.
