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?
