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.
