On the PostgreSQL piece of the post.
I have been running PgSQL for 260 days without a single glitch or restart in a 24/7 Web environment.
I had to restart it last Thursday because the machine it was running on got a hardware upgrade which required some time off the power grid, which was (of course) unrelated to PgSQL.
So in my personal experience the stability problems are a bit overstated.
