For this solution you are going to need a version of dpkg of at least 184.108.40.206.
Since that version of dpkg, there is a new
If you have an older version of dpkg you can alternatively use eatmydata.
And remember both of these solutions are unsafe and probably will lead to data loss if there is a power failure while or shortly after dpkg is running.
