Hi,
I have a array column which has 12 real values in it. Basically these
values represent co-ordinates in 12 dimensions for a substance. My main
need is to find substances similar to a particular compound. Now I can
do by calculating differences with each array in the whole table. But
the table has millions of rows. So I need some kinda higher dimensional
index. I have read about the cube operation in postgre, can it be
extended to 12 dimensions or something like that.

Thanks
Abhang
