The issue is there are certain performance benefits to be had by doing parallel CTAS operations and when converting from Oracle to PostgreSQL switching to a “COPY” operation isn’t feasible.

Copy operations are by far the most efficient way to do bulk loads. The fdw extension isn't very efficient based on prior experience.
Based on testing thus far, it appears that the only way to get a bulk load operation (similar to oracle) would be to use the COPY command or to use multiple connections and break up the inserts across connections. I did see a possibility of using the postgres_fdw extension and use the batch functionality, but I haven’t tested that yet.
Does anyone know the status of this feature / patch that was discussed in this link?
