OK, in that case I would have:
- one PG database for each Oracle/MSSQL database being transferred
- two users for each database being transferred, one "inside", one "outside"
- each user is only allowed to connect to that database from a pre-set
IP address (via pg_hba.conf)
- lock down the permissions for each user appropriately
If you want to go the procedure/function route to access each DB you can
define your DBs as SECURITY DEFINER for operations that need "superuser"
permissions.
I'd use Perl to hook it all together, but you mentioned jdbc, so
presumably you'll be going for Java.
