psql runs out of memory

In my Pentium 4 box 2GHz with 256 MB of RAM I run a pg server 8.0.3
under netbsd 2.0.2 in which among other tables  there's a "huge" table
letture02 made of 657,000 records and 98 numerical columns.

Using psql
and the "heavy" view letture24btnondom (see below) I face the following
fatal error:
..........
# select * from letture24btnondom ;
out of
memory for query result
..........

Now, it happens that I pg_dumped
the database from an original ** freebsd ** installation on another
older pc (pentium 3 128 MB) where ** under psql I set up the same query
and ran it successfully many times.
Besides, via ODBC I can open as a
table the letture24btnondom view without any problems.

What should I
do for psql?
