Looks good to me.  That should fix the problem with standbys then.


Next question: how can flipping archive_mode on and off,
with restarts, near wraparound point, break epoch on master?
 http://lists.pgfoundry.org/pipermail/skytools-users/2012-March/001609.html

Any ideas?

Could WAL playback from backend with different archive_mode setting
cause it somehow?
