I think I have solved the optimizer problem. It appears in samekeys().
Can someone check that function, and see if you come up with the same
fix I do (without knowing my fix)?
A 9-table join that used to run for minutes and fail now completes in
seconds! I want to commit this, but want confirmation from someone else
that my fix is correct.
