Huh?  walsender has no business applying any per-user or per-database

Okay. I got rid of the access to pg_db_role_setting from the patch.
I attached the updated version, which makes walsender process the
options passed in the startup packet, apply PostAuthDelay and initialize
client encoding.

OTOH, I can believe that some people would create a dedicated role for
replication and configure the parameters for replication on the role.

Right, per-database settings clearly make no sense, but per-role settings do. There isn't very many settings that make sense for walsender, but client_encoding is one example. I agree it's not terribly useful, but would be nice for the sake of completeness.

What about leaving the capability to apply per-role settings as a TODO
item?

Yeah, seems best at this point.
