Yeah, I think you are right --- this is an error in the documentation.
It should read more like

When async is true (not zero), PQgetCopyData will not block waiting for
input; it will return zero if the COPY is still in progress but no
complete row is available. (In this case wait for read-ready and then
call PQconsumeInput before calling PQgetCopyData again.)

Will fix. Thanks for pointing it out.
