Per Jay Pipes:

Patch Set 2: I would prefer that you didn't submit this

I don't think we should be adding migration files for database optimization... what works for some doesn't work for other installations with different data querying patterns. This is more DBA work.

Now, adding unique indexes that enforce *constraints* on data is another thing entirely, but I don't agree we should be doing a DBA's work in trying to prematurely predict which columns need indexes for performance reasons...
