I think we deliberately decided that we weren't going to implement this
syntax because it required this sort of pushup to provide a uselessly
redundant behavior. Adding more special cases to base_yylex is not
free, either in maintenance or in surprises for users. An example is
that trying to use LOCAL or NO as the name of a CTE will fail if this
patch is applied.
I'd like us to be trying to get rid of the special cases in base_yylex
not add more. (It strikes me that now that WITH is fully reserved,
we might not need some of the ones that are there anymore.)
