I don't know anything about the multi-db branch, but I imagine that
whatever QuerySet does to get the correct connection should work in
OracleQuerySet as well.
Note the mere existence of OracleQuerySet will still be problematic in
multi-db environments that mix Oracle databases with non-Oracle
databases, since OracleQuerySet replaces QuerySet entirely when Oracle
is used. However, OracleQuerySet is a hack that will be going away
after the QuerySet refactor, which solves both problems in the long
run.
