Ok, so one use case is to select a large number of rows and do some
non-trivial operation on them.
I can see where getting the rows inside the server process ( ie some
procedural language ) thereby reducing the round trip overhead would be
beneficial. However how do you deal with the lack of control ? For
instance what happens if you run out of memory while doing this ? I'm
not sure about other DB'S but if you crash the procedural language
inside postgres you will bring the server down.
It would seem to me that any non-trivial operation would be better
handled outside the server process, even if it costs you the round trip.
