> In ExecutorEnd, we need to restore to correct memory context after free query
> resource. There are two memory context based on PG_TRY of mppExecutorFinishup:
> 1. If mppExecutorFinishup completes successfully, the correct memory context
> is estate->es_query_cxt
> 2. If mppExecutorFinishup errors, the correct memory context is ErrorContext
> Current implementation use estate->es_query_cxt for both situation. We need
> to fix this as it may lead to core dump during memory context cleanup
> afterwards.
