I had a look on pg catalog tables http://www.postgresql.org/docs/8.4/static/catalogs.html to create a stored procedure to do this job for me. I have found some tables which might be useful to get the original table iformation. For example, I can use pg_table to get the owner of the original table. Also, I have found pg_roles. However, I was not able to find where the access privileges are stored.

You are looking for pg_catalog.pg_class.relacl. Just copy that from the original table to the duplicate (and perhaps relowner, depending on your situation), and you will have duplicate permissions.
