See psql's FETCH_COUNT. From the manpage:

       FETCH_COUNT
           If this variable is set to an integer value > 0, the results
of
           SELECT queries are fetched and displayed in groups of that
many
           rows, rather than the default behavior of collecting the
entire
           result set before display. Therefore only a limited amount of
           memory is used, regardless of the size of the result set.
