Hmm, I can't see what's different there than what I get on my test
program. Can you please do PQtrace() on the connection and send the
resulting trace file? Maybe I can compare the traffic to understand
what's the difference.

(I do see that you're doing PQisBusy that I'm not. Going to try adding
it next.)
