Any more thoughts on this?

The file being produced when dumping the table in question is about 1
gig when it crashes.  In the last check-in for fe-protocol3.c, there's
notes about 1 gig strings so I'm wondering if my data when received by
pg_dump (or output by the 8.3.1 server) goes over?  270m of bytea
converted to \xxx octal strings would make something > 1 gig.  But the
270m is spread over 400 rows with nothing bigger than 3m.

If there's no interest in researching this any further, then I'll stop
the server and take a file system copy of the data directory and upgrade
it to 8.3.3 and pray the problem goes away.
