Why not something similar what exists for database variables? i.e.
option=>value.
As for having them as child nodes of a foreign server, I think that
would work well. Each node member would be a user, and wouldn't the
oid from pg_user_mapping be available to display in the properties.
You'd then have oid and options. Granted it looks very minimalistic,
but then I think it's more intuitive.
