Thanks.  Now I realize what should have been obvious:  the command "COPY
BINARY" is being executed by the backend, while PQputline() is a frontend
routine. Duh.

However, this is an embedded system, so some modest amount of backend-hacking
is quite acceptable if the payoff is large enough. Do you have any pointers on
implementing a variant of COPY BINARY <> FROM file that works out of memory
instead of a file?
