Default mode for shutdown

I'm sure this has been up before, but hey, let's take it another round.

Why don't we change the default shutdown mode for pg_ctl from "smart"
to "fast"? I've never come across a single usecase where "smart" is
what people *want*... Not sure if others have?

Yes, I realize it's somewhat of a backwards compatibility thing - but
it will at least not change things for most packages, since I believe
all those use "fast" anyway.
