I'm trying to establish whether or not that's the only reason. It might be okay to use the same item pointer struct as the representation of a integer-like logical identifier. Even if it isn't, I'm still interested in just how logical the TIDs are, because it's an important part of the overall design. > That's one of the reasons why I've been trying to get you to get on > board with allowing different leaf-level "item pointer equivalents" > widths inside nbtree... Getting me to agree that that would be nice and getting me to do the work are two very different things. ;-) -- Peter Geoghegan
