[PATCH] Log crashed backend's query v3

Hi,

My apologies for the last grumpy message I wrote; I sent it out of
surprise that my patch was marked "closed" on the current commitfest.
I hope I haven't discouraged you from reviewing this updated version.

I think you intended to use the "Waiting on Author" status -- that
leaves the commitfest entry open. I will re-open the commitfest entry
myself, I hope that's OK.

Here is version 3 of the patch.

This is now fixed in the patch.

I wasn't entirely sure which line you're referring to (what's on line
2725 in the current git master wasn't touched by me)
But I presume it's this statement:
if (activity < BackendActivityBuffer || ...

I have rearranged this if statement using a temporary variable so that
there's no need to right-align long expressions anymore.

I also tweaked the wording of comments here and there.

For the points not addressed in this version, see my response here:
