I think we'll need to do something about the width of varatt_external to make
the conversion to 64bit toast oids viable - and if we do, I don't think
there's a decent argument for staying with 4 byte toast OIDs. I think the
varatt_external equivalent would end up being smaller in just about all cases.
And as you said earlier, the increased overhead inside the toast table / index
is not relevant compared to the size of toasted datums.
