Thanks, this it exactly.

Correlated, is there a way to define a fdw user mapping for a role versus for every single individual user in a database?

No, and it's unlikely anyone would ever put effort into making dblink
do that, because the newer foreign table (FDW) code *does* handle that
sort of thing.  dblink still has its uses, but it's pretty much at a
dead end developmentally.  Take a look at postgres_fdw.
