That's precisely what I'd expect: the backend will process the query and
begin sending back the entire result set to the client. The client will
attempt to allocate a local buffer to hold the entire result set, which
obviously fails in this case.
You probably want to explicitly create and manipulate a cursor via
DECLARE, FETCH, and the like -- Postgres will not attempt to do this
automatically (for good reason).

You should consider upgrading, 7.3 is quite old. At the very least, you
should probably be using the most recent 7.3.x release, 7.3.11.
