After digging around a little, I remember that there are a *bunch* of places in fe-protocol3.c that advance inStart. The cleanest way to shove this stuff in without rethinking that logic would be to call pqTraceOutputMsg immediately before each such advance (using the old inStart value as the message start address). A possible advantage of doing it like that is that we'd be aware by that point of whether we think the message is good or bad (or whether it was good but we failed to process it, perhaps because of OOM). Seems like that could be a useful thing to include in the log. Or we could rethink the logic. It's not quite clear to me, after all this time, why getRowDescriptions() et al are allowed to move inStart themselves rather than letting the main loop in pqParseInput3 do it. It might well be an artifact of having not rewritten the v2 logic too much. regards, tom lane
