In general it is not very difficult, there are exceptions of course but
it is more time consuming than difficult.

You can use Orafce:

http://pgfoundry.org/projects/orafce/

This will get you a lot of compatibility with data types and function.

The #1 complaint I hear about migrating to Oracle is the lack of the
Oracle feature Packages. Some of this can be simulated (very little)
with the use of schemas but for the most part you should just consider
rewriting all your procedures in your favorite pl language.
