That's not what I think it meant: I don't wish to do the complicated
approach either anymore. I sent two patches on the mail mentioned
above: one for master/9.5 that used the approach of changing WAL, and
a second aimed for 9.4 and old versions that is close to what you
sent. It looks that you did not look at the second patch, named
20151209_replay_unlogged_94.patch that does some stuff with
XLOG_HEAP_NEWPAGE to fix the issue.
