Re: tuple count and v3 functions in psql for COPY

I've just realized an exception in the sending data while using
PQsendCopyData(). Function's blocking behaviour is not guaranteed,
therefore a

    if (PQisnonblocking())
        PQsetnonblocking(conn, 0)

kind of phrase required before using PQsendCopyData(). But after a
small investigation, found that both psql and pg_dump runs in
blocking mode - without any PQsetnonblocking() call. Thus, AFAIC,
above phrase isn't necessary.

FYI. Just wanted to inform. Any comments are welcome.


Regards.
