Renaming column name with index generates wrong migrations

[jeroen11dijk]

I had a resource with a start_date with an index but I renamed it to date and while generating the migration it switched the order around by first adding an index before renaming the column which will result in a crash.

def up do
    drop_if_exists index(:events, [:start_date])

    create index(:events, [:date])

    rename table(:events), :start_date, to: :date

    alter table(:events) do
      modify :date, :date
    end
  end
