Right, which is exactly what you would expect. The entire result set is
sent to the client and stored in local memory; if you only want to
process part of the result set at a time, use a cursor.

(And I'm a little suspicious that the performance of "SELECT * FROM
big_table" will contribute to a meaningful comparison between database
systems.)
