    Here, we can see that there is a gain of ~15% to ~38% at higher
    client count.

    The attached document (perf_write_clogcontrollock_data_v6.ods)
    contains data, mainly focussing on single client performance.  The
    data is for multiple runs on different machines, so I thought it is
    better to present in form of document rather than dumping everything
    in e-mail.  Do let me know if there is any confusion in
    understanding/interpreting the data.

Forgot to mention that all these tests have been done by
reverting commit-ac1d794.

This patch no longer applies cleanly:

$ git apply ../other/group_update_clog_v6.patch
error: patch failed: src/backend/storage/lmgr/proc.c:404
error: src/backend/storage/lmgr/proc.c: patch does not apply
error: patch failed: src/include/storage/proc.h:152
error: src/include/storage/proc.h: patch does not apply

It's not clear to me whether Robert has completed a review of this code or it still needs to be reviewed more comprehensively.

Other than a comment that needs to be fixed it seems that all questions have been answered by Amit.

Is this "ready for committer" or still in need of further review?
