If you want a GPL version of Oracle look at http://www.sapdb.org .  Did
I mention that GNUe supports SAP-DB. ;)  If you need a SAP-DB I have
about 100 or so en route to the house and probably 4 or 5 laying in the
office if you want one.

I dont think thats correct, but its neither here nor there you should
use SAP-DB. ;)

This pg_hba.conf is your friend and depending on how you create users
will dictate what they can or cant create by default.

Postgres is far from perfect, but it can do what you want, unless I have
misunderstood the issues.
