It's a partial template specialization and not all compilers support
that well enough. I know that you can work around this and I don't
want to be a spoilsport, but I think this is a too intrusive approach
for the limited purpose it satisfies. What about exception safety
regarding the call to postconstruct, for example? What if a derived
class implements postconstruct for its own purposes and doesn't
forward it up the class hierarchy? Wouldn't you need a predestruct
for this to be usable for more than your specific needs?

I think you're better off writing a specialized smart pointer if you
want that kind of functionality.
