Not in the linked source I gave, as well as this one, but it's possible that in some versions they are different (although I have not encountered one yet). I know that the LXX Psalms are not numbered the same as those in KJV.
By the way, that KJV translation isn't even close to the LXX Greek. You're right
I know. :) ... (oops, there goes my confession!)
Here's the one I was looking at:

There's another one in Greek with the same numbering system

I'll read them tonight and see where mine double up on a verse.
