Hi,
I don't think an oracle dump file will work with PostgreSQL. You could look at tools like ora2pg which will do both - pull data/procedures from Oracle and then load into PostgreSQL. It also provides a lot of flexibility so that you could change the in-built data type mapping from Oracle to PostgreSQL. You could also have a look at orafce so that your Oracle codew with sysdate/dual etc work in PostgreSQL.
If you are looking for continuous replication from Oracle to PostgreSQL, rather than a one time migration, GoldenGate should do the job. There may be inexpensive alternatives to GoldenGate.

I'd suggest forgetting about the fact you are migrating an existing
application to PostgreSQL and approach it from a fresh-start perspective and
learn generally how PostgreSQL operates. Once you have a feel for how
things correlate the migration should go much more smoothly.
EnterpriseDB (with whom I am in no way affiliated) seems to have setup a
focus for itself in supporting Oracle to PostgreSQL migrations. Other's may
be capable as well but they, IMHO, at least have done the best job marketing
that niche...The most recent version usually - 9.3; 9.2 if you dislike .0 releases.

Since you are migrating I'd suggest 9.3 regardless because by the time you
are ready it'll probably be at least a .2 release.No clue; though doubtful. Even if technically capable of being used for an

import inherent language differences would likely cause the SQL commands to
fail. Again, this is a problem that has already been addressed and I would
generally advise paying for someone else's experience rather than trying to
figure it out on your own while asking for no-charge help from the
community.
Disclosure: I have only minimal scanned the net for this kind of material,
and have never used any of it myself.
