After reading the related threads and code, I'm inclined to agree that this
is a mistake, or at least that the current wording is likely to mislead
folks into thinking it has something to do with parallel query. I noticed
that your patch changed a few things in the description, but IMHO we should
keep the fix focused, i.e., just replace "end of a parallel operation" with
"transaction end." I've attached a modified version of the patch with this
change.
Thanks for the feedback Nathan.
I think it is important to indicate that the group leader is responsible for clearing the transaction ID/transaction status of other backends (including this one).
If you suggest that we keep it simple, I don't see any other issues with your patch.
