Perhaps I've missed some subtlety, but I'm not sure that it's all that
ugly. If splitting INTERNAL_AUTO into two new dependency types amounts
to the same thing as what you suggest here, then what's the
difference? If this secondary INTERNAL_AUTO entry property can be
determined from the pg_depend record alone with either approach, then
it's not obvious to me that an "explicit representation" buys us
anything. Yes, you must introduce a special case...but isn't it a
special case either way?
