Great, thank you. I pushed it after modifying it a bit -- instead of
throwing the error in MergeAttributes, I did it in
AddRelationNotNullConstraints(). It seems cleaner this way, mostly
because we already have to match these two constraints there. (I guess
you could argue that we waste catalog-insertion work before the error is
reported and the whole thing is aborted; but I don't think this is a
serious problem in practice.)
