You mean something like

        if (input-buffer-not-empty)
                parseInput();

?  This still bothers me a bit since it's a mixing of logic levels;
PQputCopyData is an output routine, it shouldn't be getting its fingers
dirty with input buffer contents.  I'm willing to tolerate this if it
can be demonstrated that it provides a useful performance gain compared
to the unconditional parseInput call, but let's see some numbers.
