Pretty delayed, but please find the attached patch that addresses all the issues discussed.
The docs on this v4 look like they suffered a patch order problem here. In the v3, you added a whole table describing the pg_stat_activity documentation in more detail than before. v4 actually tries to remove those new docs, a change which won't even apply as they don't exist upstream.
My guess is you committed v3 to somewhere, applied the code changes for v4, but not the documentation ones. It's easy to do that and end up with a patch that removes a bunch of docs the previous patch added. I have to be careful to always do something like "git diff origin/master" to avoid this class of problem, until I got into that habit I did this sort of thing regularly.

I did a 'backwards' diff last time. This time around, I diff-ed off of a fresh pull of 'master' (and I did the diff in the right direction.
Also includes whitespace cleanup and the pg_stat_replication (procpid ==> pid) regression fix.

Okay, I'll fix that and the rules.out regression that I missed
