I would be happy with any mechanism at all which would enable me to cope with such non-conforming databases. What's the Right Thing to do?
The problem is that Postmodern went with a 'simplify Lisp symbols to get credible SQL names' scheme that assumes those credible SQL names are not escaped. Some major touching up would be necessary, both in the dao metaclass code and in s-sql, to make it possible to get around this assumption.
