Well, let's leave it as a difference of opinion for the moment.
I do agree that improving the names generated for expression indexes
would be useful independently of this.  I propose setting this patch
aside for the time being, and I will go look into that, and then
if that gets accepted we can come back here and discuss how much
of a problem remains.
