I think this is a really bad idea, because it destroys libpq's basic
concept that you get either success or failure for a command. Peeking
at a partially-arrived result might give you back some rows only to get
an error later (since the backend may fail partway through a query).
I'm not sure that the partially constructed result is valid anyway;
the last row may be in a funny state. And what happens if the
application does a PQclear() on it??
