Ooh, you mean it doesn't give you the rest of the data before reporting
EPIPE? That seems so broken it's hard to believe --- a whole lot of
programs would be falling over, not just Postgres. There's probably
something else happening here, but I'm not real sure what. Might be
worth checking to see exactly what's in libpq's input buffer at the
time it sees the EPIPE error.
