AFAICS, this is only important in places where the syntax allows either
a keyword or an identifier. If only a keyword is possible, there is no
value in rejecting it because it's quoted. And, when you do the test,
I think you'll find that it would be breaking hba files that used to
work (though admittedly, it's doubtful that there are any such in the
field).
