This question may betray a limited understanding of Postmodern or PostGres; but. . . .

If possible, how can Postmodern be used to generate queries that can interact with capitalized/mixed-case table and column names?

It appears that in postgres, unless double-quoted, a string is converted to lowercase (as with lisp with uppercase). String literals are single-quoted to SQL literals, not double-quoted as appears required for names.

Postgres appears to lowercase even symbols containing capitals (e.g. |AbCd|)

If no mechanism for mixed-case exists, would the use of mixed-case symbols be an appropriate change to make to PostGres?

Thanks, Matt
