You can use any database that has a JDBC driver, using whatever setup the database/driver supports. I don't think Lift can detect things like removed fields. Schemifying is great for initializing the database and making sure everything that will be expected to be in the database is created if it doesn't exist yet, but sometimes you just have to modify it directly.
