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 surprises
2. pg_upgrade makes future data format changes problematic
3. 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.
