Yes we take some of the burden: we do not use MYSQLisms, we make sure that the queries validate --this can be part of the new policy, something positive that came out of this talk -- we check the postgresql manual if we do something funny -- there is just the actual test we are talking of. I do not think our viewpoints are too far away :)
