You could look at or2pg script provided in postgresql sources, contrib section. It might do the trick for you.
I would request you to join postgresql-general mailing list at http://www.postgresql.org/lists.html. You could get further help you need in your migration.

Hello friends,
We would like to convert our Oracle database to the free PostreSQL RDBMS. I would like to know the best way to export Oracle data so that I can load the data into PostgreSQL. Is there a text export in DDL statments emmbeded?
Background: We are nearing the end of a 2 year term license for Oracle Standard Edition and we would like to move to something more cost effectivive. We would also like to run our database on a machine with more than one processor. I think it cost too much for a Oracle 4 CPU license. Since PostgreSQL is free, I can run in on a 4-way or 8-way machine without having to pay much more money.
Also PostgreSQL seems to be the most compatible OSS database. It has similar triggers, PLSQL, stored procedures like Oracle etc. I also liked the ability to write stored procedures in Perl and Python and TCL. Also unlike Oracle, PostgresSQL does not come with a big Java JVM bolted on. Also the .ORG domain
We ruled out MYSQL since it was the least like Oracle.
The Karen Southwick article was very informative too. http://news.com.com/2010-1071-5072299.html
If PostgreSQL is good for .ORG registry then it is good enough for me: http://www.isoc.org/dotorg/10-1.shtml
"Sustaining the high-availability infrastructure that delivers this
performance is one of the most advanced open source relational database
systems, PostgreSQL. As detailed in our answer to Question 13,
PostgreSQL already fully supports a 24x7, high-transaction, registry system:
1. it has scaled with .INFO from zero to nearly one million domains via its large capacity and its concurrency capability (multi-version concurrency control); 2. it provides all database functions required by .INFO (and .ORG); 3. it delivers (as evidenced above) at our service level commitments or better; 4. it benefits from broad usage (RedHat, BASF, and others) and support by a significant base of developers; and 5. it provides high data portability and standards compliance, including native JDBC/ODBC support."
Thank you for your help.
