I think there are a few reasons this has been delayed, aside from the
scheduling ones:
1.  compression issues were a surprise, and we are wondering if    there are any other surprises2.  pg_upgrade makes
futuredata format changes problematic3.  9.3 multi-xact bugs spooked us into being more careful
 

I am not sure what we can do to increase our speed based on these items.
