Looking at the context of the chapter it is about suffering and a curse being wished upon a group of people or a city.
If you think of quick as in "alive", with "quickened" meaning "made alive" and drop the last part of that word and have it just mean "alive" [and not in the verb sense like "quickened" is], I would assume that means David is praying to have these people or this city thrown into hell alive instead of dying first - just a more intense way to pray for God to curse them.
"And you hath he quickened, who were dead in trespasses and sins; " Ephesians 2:1 . But then again with that verse it seems like the lost don't have their spirits made alive before they are thrown into hell. Maybe it's only talking about their bodies and not their spirits in that verse in Psalms.
