For sure. The only saving grace of the multiple-calls thing is that it
allows you to cope with indefinitely large result sets ... and we're
blowing that advantage by stuffing the result into a tuplestore back
at nodeFunctionscan.c, anyway. I still want to revisit that set of
issues someday soon (not for 7.3 of course).
