What would you do in the following situtation:

You are approaching a non towered field, communicate right and all that
stuff, your on final, suddenly a cessna pulls up and starts it's take
off roll.

Also lets bring the same situation to a towered airport where the
controller tells you to go around while you are on final.
I am asking this because I am just wondering that at some point the
aircraft could collide (one climbing out, the other at pattern
altitude), and what the pilot going around should do...

Power up, pitch up, flaps up.
If you are in a retract, leave the gear down, your Vx and Vy speeds will
be lower and you won't have to worry about forgetting in on the next
circuit.
Fly to the right of the departing aircraft.
Allow the departing aircraft to accelerate ahead of you.
Turn left, enter the pattern and land normally.
Why follow the departing aircraft?
You are ready to land.
