Could you keep the sequence unchanged for non-EXPLAIN callers with some 
refactoring? Add an exposed function like ExecutorFinishRun() that 
Explain calls explicitly in the EXPLAIN ANALYZE case, and modify 
ExecutorEnd to call it too, if it hasn't been called yet and the 
explain-only flag isn't set.
