The resulting library is on github: https://github.com/EDS-APHP/spark-postgres
While there is room for improvements it is also able to read/write postgres
data with the COPY statement allowing reading/writing **very large** tables
without problems.

Hi
The spark postgres JDBC reader is limited because it relies on basic
SELECT statements with fetchsize and crashes on large tables even if
multiple partitions are setup with lower/upper bounds.
I am about writing a new postgres JDBC reader based on "COPY TO STDOUT".
It would stream the data
