You're definitely right; the current behavior is painful in some
cases. Using a cursor is the typical solution, in cases where it's
possible. The change you have in mind is on the TODO list (cf.
http://wiki.postgresql.org/wiki/Todo, "Allow statement results to be
automatically batched to the client"); it hasn't been tackled at this
point.
