No. Continue with the vote.
Allowing the Democrats yet another concession in a never ending string of concessions is ludicrous.
The FBI has already done their investigation.
This delay will result in a better turn out for Democrats and a better chance that after the elections, none of Trumps nominations will get confirmed.
If Kavanaugh fails confirmation, the Right will be enraged and the voter turn out will be better in November, hopefully taking more seats in Congress and assuring no obstructions after the elections.
AFAIK, there is nothing saying Kavanaugh could not be nominated again AFTER the elections.
Or worst case, Trump can choose one of the further right wing nominee candidates.
The war we are in is a matter of who sits on the Supreme Court.
