It is theoretically possible, but depending on your skill level, possible
but difficult.
Starting with the latest versions of PostgreSQL, it is possible to return
multi-column result sets. All one would need to do is construct a
PostgreSQL extension that would query the Oracle database and return the
result set.
But, in general, I'd say no.
