If we believe that, why isn't the default value of use_remote_estimate true?
(Maybe it should be.)
Another option that should be considered is that joins should pay
attention only to the server-level setting and not to the individual
tables' settings. This would surely be cheaper to implement, and
it avoids any questions about whether to OR or AND the individual
settings.
