Why transformTargetList? The comment above this function says that it's
indiffernet if there is a SELECT or INSERT or an other stmt. being parsed -
the expressions are just to be transformed? Woudn't it break this
indifference if I add a new branch handling with the Default node to this
function? Or is it uncritical if I simply add it without any distinction of
what stmt. is being parsed? Could it become a problem later if the Default
node is reused by some other stmt.?
