Hello,

Do you mean about this GreenPlum database?
https://docs.vmware.com/en/VMware-Greenplum/7/greenplum-database/admin_guide-external-g-foreign.html

We do not have special experience and knowledge using this technology.
And by the above document, it may work but it seems to have some restrictions.

Most PostgreSQL foreign-data wrappers should work with Greenplum Database. However, PostgreSQL foreign-data wrappers connect only through the Greenplum Database coordinator by default and do not access the Greenplum Database segment instances directly.

I'm sorry, there is no information about how to use in GreenPlum.
I think you should ask it GreenPlum community or product support.
