I'm sorry, it wasn't clear from my earlier post that the triggers are dependent on a function provided by the extension.
So when you do CREATE EXTENSION foo, it creates foo_somefunc() that RETURNS TRIGGER. Later, a trigger is created (somehow; in this case it is by some other function in the extension, but it could be by the user directly as well) that executes this function. But that's only a partial answer to the questions raised here, and I'll return to the drawing board and draw up a more complete explanation.
