one heads-up is Archive/DW DB may need to build WITHOUT CONSTRAINTS

May need to introduce ARCHIVE system/tag in pg_hba.conf

there's a whole lot of implied magic here unless you want to get way more specific what these features do, exactly, under all possible conditions.

I'd go further than that and say I can't see how something like this could possibly work with physical (block based) replication. It's total hand-waving.
