Either this patch, or something else committed this morning, is

it's this patch, because I attached to a backend and stopped it a few
times, and all the backtraces look like this:
Yeah, sure looks like it's the group commit commit. It works for me, and
staring at the code, I have no idea what could be causing it. The
buildfarm seems happy too, so this is pretty mysterious.
And just after sending that, I succeeded to reproduce this. I had to
lower wal_buffers to a small value to make it happen. I'm debugging this
now..
It was a bug in the LWLockRelease code, after all. Fixed. Unfortunately
this added a couple more instructions to that critical codepath, but I
think it should still go without notice. Let me know if this doesn't fix
the hang on your laptop.
