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..
