The fastest and easiest method would be to dump the data from Oracle into CSV/delimited format using something like ociuldr (http://www.anysql.net/en/ociuldr.html) and load it back into PG using pg_bulkload (which is a helluva lot faster than COPY). Of course, you could try other things as well... such as setting up generic connectivity to PG and inserting the data to a PG table over the database link. Similarly, while I hate to see shameless self-plugs in the community, the *fastest* method you could use is dblink_ora_copy, contained in EnterpriseDB's PG+ Advanced Server; it uses an optimized OCI connection to COPY the data directly from Oracle into Postgres, which also saves you the intermediate step of dumping the data. -- Jonah H.
