I'm a huge Postgres fan, but... 1. Migrating is a huge, difficult, expensive project at Github's scale -- almost as bad as a rewrite 2. "Can handle more data and load" doesn't make sense as a blanket statement How much data and load Postgres can handle vs MySQL is determined by lots of variables. It's neither absolute nor consistent. It depends more on database and infrastructure design than on the underlying RDBMS. The best reason to choose Postgres over MySQL is not hardware efficiency but rather developer efficiency, although some projects get both.

"Changing the tires on a moving vehicle" but the moving vehicle is one of those road trains in Australia with 50 tires.

  Wouldn't it actually get easier to move the tires on a vehicle with a lot of them? You can't change the tire on a unicycle while moving, but it would theoretically already be possible on a motorcycle if you can wheelie long enough (the back wheel is more difficult) and each wheel beyond that just adds more stability and redundancy.
