Thanks, Mithun for performance testing, it really helps us to choose the right strategy here. Once John provides next version, it would be good to see the results of regular pgbench (read-write) runs (say at 50 and 300 scale factor) and the results of large copy. I don't think there will be any problem, but we should just double check that. > Good to hear.
