It depends on what you're trying to achieve.
Your way might work if you only want to mirror oracle -> pgsql but not vice
versa.
Furthermore you need to do manual maintenance on the pgsql side if you
change your schema on the oracle side (create/drop/change tables, ...)
I've done something similar with MS SQL -> pgsql and perl some years ago.
Shout if you're interested.
There's also dbmirror in contrib/ that works in a similar way.
