Check out ora2pg. You can use this perl tool for data migration as well.

Also, While you are converting your DDL and other queries, you could run
'explain analyze' on them to see how good they perform and make
appropriate changes for better performance.
Btw, glad to see that you are planning to move to PG. :)
