missing call to InstrEndLoop

[tvondra]

pgqs_ExecutorEnd gets called before regular ExecutorEnd, which means the instrumentation may not be finalized - there may still be data from the last loop in some of the nodes. pgqs_collectNodeStats needs to do something like this:

if (planstate->instrument)
	InstrEndLoop(planstate->instrument);

similarly to ExplainNode().

Indeed. I wasn't aware of that, thank a lot for the report and the fix! It's fixed in 7ad33fb
