Sounds reasonable. I wonder if this should be backpatched -- ISTM the
proper representation of the view is with an explicit FROM list anyway,
and making the correctness of view definition dependent on a GUC
variable is only asking for trouble.

pg_dump could itself specify "SET add_missing_from = true" before view
definitions. However, that is definitely a hack :(
