[ shrug... ]  In principle you could write a client library that would
act that way, but I think you'll find that none of the extant ones
will hand back an incomplete query result to the application.

A possibly more convincing argument is that with that approach, the
connection is completely tied up --- you cannot issue additional
database commands based on what you just read, nor pull rows from
multiple portals in an interleaved fashion.
