The patch mentioned there is in 8.2 and up. There are various other
patches that have gone in at different times to try to address other
contention issues. With so little data as this it's hard to tell
exactly what problem you hit. So, if you're going to consider a
major-version migration in hopes of solving a performance problem of
this kind, it'd likely be a good idea to go to 8.3.x instead of 8.2.x.
