we respect the level of conservatism in Postgres and expect that this could take a while to upstream. we're committed to any timeline and we'll develop it for self-hosters and on the supabase platform first to iron out all the bugs
that said, even if it remains an extension that's fine: as long as the TAM patches land upstream this enables everyone to create storage engines using an extension approach - a very "postgres" way of doing things
