Hi,
I've been exploring the new FDW API in the past few days, and I'm slightly
confused by the fdw_private fields. A few comments:
1) Generally all the API functions pass data using fields in the nodes
(e.g. GetForeignRelSize uses baserel-fdw_private etc.), but
PlanForeignModify simply returns

2) Is there any particular reason why PlanForeignModify/BeginForeignModify
require the fdw_private to be a List*, and not a generic pointer?
That data has to be copiable by copyObject(), which a generic void* is
not. We could perhaps have made it Node*
