- RenameIndex can be reduced into CreateIndex
- DropConstraint can be reduced into CreateConstraint
- A question was raised whether constraints could be reduced into create
model though some databases do not support deferrable constraints (eg
MySQL)
- It's worth going over the operations to see if there are any other
potential reductions to add
