- schema change to allow tl_namespace and tl_title being empty This is done by removing them from primary key. They don't need to be nullable as they have default value. - Make sure with WRITE_NEW, updater avoids writing to the old columns Bug: T306674 Change-Id: I2b8a29043e952060e7a79b6a7a3d647d48cd16fb
