Indeed, that is one option. Because the syntax is WITH [ LOCAL |
CASCADED ] CHECK OPTION, ISTM we'll actually need three new tokens:
WITH_LOCAL, WITH_CASCADED, and WITH_CHECK, which is even uglier :-( Per
a suggestion from Dennis Bjorklund, it might be cleaner to introduce a
lexer hack for the places where WITH can occur in a SelectStmt, which I
believe is just WITH TIME ZONE.

It would be unfortunate to revert the change, but I doubt the overhead
is very significant. Does anyone have any better suggestions for how to
resolve the problem? (My Bison-foo is weak, I have to confess...)
