It's not really that easy, because postgres_fdw (like the server in
general) is running as the database-owner operating system user.
How will you associate a Postgres role that's responsible for a
particular connection request with some Kerberos credentials,
while keeping it away from credentials that belong to other roles?
This is certainly something that'd be useful to have, but it's not
clear how to do it in a secure fashion.
