Sure there is! There are queries that benefit from having a temporary table created for a subquery and the temporary table indexed before the join. Since we can't easily return result sets from functions yet, it's not probably used that much, but from within a function, I can see why you might want to do this from time to time.

I'm kind of surprised that it's possible to index a temporary table.
There's not much point in doing so.
Yes, the indexes would be dropped as well.
