I prefer to call it "optimistic prediction". But yes. :)

Thanks, but it's too late in retrospect. Since that is the case, to whom can I make a feature request that initdb have an implicitly enabled option to make this base backup?
OK, back to question. Provided the system is the same, the postgresql executable and libraries are identical, the locales are unchanged, we have:
1. bitwise variances in the system catalog
-- can be solved with David's suggestion of full dump/restore after the steps I listed. Confer?
