Actually, thinking more about this, I am wondering if we should not
remove the DEFAULT expression productions in gram.y. Maybe we can
keep the syntax and give an unsupported error during parse-analysis,
like the last version of the patch did for DEFAULT ON EMPTY. Which
also means to also leave JsonBehavior alone but with default_expr
always NULL for now.
