According to the the tuning document released by GreatBridge, postgres
is relational as well as object oriented. Since it is object-oriented
methinks it shouldn't be a problem to translate a DTD to a database def,
but trying to figure out the postgres backed code gives me a headache.

Basically what is needed:

1) A parser to create a database schema from an XML DTD.
2) A parser to translate SELECT /root/element1 FROM table WHERE
/root/element1(at)param1 = "foo"; into a database query. Could be tricky
because (I think) element1 has to be stored in an array field because
there might be more than one of them, and I'm not sure how to do a
select on an array element. I really don't know how the
object-oriented-ness of postgress works, the only docs only seem to
cover the relational paradigm.
