ETLtools allow users to compose a data loading job from multiple steps: data input, transformation, data output, etc.
Iguess the user can't directly incorporate ALTER TABLE into the data output step, and has to add separate custom steps
forALTER TABLE. That's burdonsome and forgettable, I think.
None of the arguments presented here has done anything to change my
opinion that adding a 'none' WAL level is a bad idea.
