No, that error text only appears in libpq, so it's happening on the
client side --- pg_dump just doesn't know the difference between an
error sent from the server and one generated within libpq.

My guess is that there's some extremely wide row(s) in your database.
The client-side libpq has to be able to buffer the widest row during
a COPY, and your client machine doesn't seem to be up to the task...
