Description
From https://github.com/django/django/pull/16819#issuecomment-1529913703
- 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
