        Unfortunately, it seems like Oracle constructs a DBMD with all the
metadata up front.  So perhaps it isn't the greatest implementation.

        Okay, as soon as I get a chance I'll look into this.  I have
PostgreSQL installed (RedHat did it for me), but no idea how to use it.  
Can you give me a 30-second overview of creating a DB and user and then
I'll try this out.  I think I should use PostgreSQL because you can't roll
back a table create in Oracle...

        Because all together those database products have what, 5% market
share?  And that's probably being generous.  If our product doesn't work
with Oracle, it doesn't work.
