That data has to be copiable by copyObject(), which a generic void* is not. We could perhaps have made it Node* instead, but that would only work conveniently if there were infrastructure for plugins to create new first-class Node types; which there isn't. A List is often the easiest way to transport a few random values from plan time to execution time, so it seemed best to declare fdw_private that way. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
