I would say the outer-most.  If people inbetween want to mess with
things, let them qualify it before handing it down.  Clearly, an
already-qualified object would be left alone.

At least at the moment in our application code the search_path is set
quite far apart from the function call.  Additionally, we depend on the
fact that we can set a multi-schema search_path with a specific order
and have the correct thing happen.  A function which qualified an object
based on the current search_path would probably work for us in this
application but seems quite counter-intuitive to a user who is calling
functions by hand (for whatever reason).


select error_scan(pg_getfullname('default_error_list'));


select error_scan('default_error_list');

As a user, it's pretty ingrained that unqualified table names follow the
current search_path and having to explicitly qualify tables when passing
them to functions (with a helper function or not) just comes across as
