Here is advice from Georgena Terry, founder of Terry Precision Bicycles, about silencing a squeaky saddle:

By the way, T9 is a waxy substance not made to stop squeaks, but to provide a filmy protectant against rust and dirt.

WD40 is a lubricant that could work on your saddle rails. Use a small amount. This is might be the easiest fix. (Don't use WD40 on other components of your bike, only the seat parts -- not the chain.)

Silicone sprays sometimes aren't intended for metal-to-metal surfaces, so check out the product specs if you're going to buy one of those.
