Hmm, I disagree. It should be the job of ExecParallelRetrieveInstrumentation to allocate its data in the correct context, not the responsibility of nodeGather.c to work around the fact that it doesn't. The worker instrumentation should be allocated in the same context as the regular instrumentation information, which I assume is probably the per-query context.
I agree, this make sense.
Here is the patch to allocate worker instrumentation into same context as the regular instrumentation which is per-query context.
