I don't have a particular interest in the Oracle gw, but am interested
in getting simultaneous multiple db access within Postgres. I had been
thinking of trying to implement this as a Postgres "master database"
with hooks deeper in the backend to call out to a remote database as a
separate session. Sort of like Ingres implemented their distributed
databases. Haven't done anything with it though...
