Not too surprising.

It's really a libpq design issue: since libpq provides random access to
a PGresult, and has no mechanism for handling failures after returning
the PGresult to the client, it has to slurp the whole query result into
memory first.

FWIW, there's a feature in CVS HEAD to instruct psql to try to use a
cursor to break up huge query results like this.  For the moment I'd
suggest using COPY instead.
