What'd be a good name for the GUC controlling this,
missing_column_as_warning?

I don't know about others, but I've previously had the idea of having more warnings like this (my go-to example is  DELETE FROM foo WHERE bar IN (SELECT bar FROM barlesstable);  where "barlesstable" doesn't have a column "bar").  Perhaps it would be better to have a guc with a list of warnings, similarly to what we did for plpgsql.extra_warnings?

Now that I start thinking about it, more ideas for such warnings start springing up..
