Junk attr yes, "fixed system column number" no. That's not how
junk attrs work. What it'd need is a convention for the name of
these resjunk attrs (corresponding to ctidN, wholerowN, etc).
We do already have tableoidN junk attrs, but by the same token
those should always be local OIDs, or we'll be in for deep
confusion. Maybe "remotetableoidN" ?
