Scheme-PG, http://scheme-pg.sourceforge.net, provides access to
the PostgreSQL RDBMS and might meet your needs.

We use it regularly, and it has been updated to 299.30, but I hadn't
posted the new version yet, however, your post prompted me to do so.

If you give it a try, let me know how if you have any questions.

Cheers,
David
