WMF DBAs have been doing a massive effort to convert UNIQUE KEYS into PRIMARY KEY. Having a PK is essential to do maintenance, specially on large tasks. By not having a PK it is impossible to add it in a safe way if not done directly on the master. Having a PK means that we can easily change the PK into another one if needed in the future. The ones we chose might not be the best ones, but will allow us to get them changed. Bug: T172514 Change-Id: Id635297838938c7c5dfe65d45285a4d16d65152d
