It appears that something is still wrong. I applied lipq pipeline v27 from [1] and ran src/test/modules/test_libpq/pipeline singlerow, after patching it to do PQtrace() after PQconn(). Below is the output I get from that. The noteworthy point is that "ParseComplete" messages appear multiple times for some reason ... but that's quite odd, because if I look at the network traffic with Wireshark I certainly do not see the ParseComplete message being sent three times.
