It's possible, but it doesn't make sense. A unique index is a normal 
index with an added unique constraint. Adding another index on the same 
field would make no sense (unless the field is a rightmost part of a 
unique index).

Your question would have been answered by checking the archives less 
than a week back (this question comes up a lot) or reading the manual.
