Actually, I think it's better if all the resets of attnotnull occur in
RemoveConstraintById, for both types of constraints; we would keep that
block in dropconstraint_internal only to raise errors in the cases where
the constraint is protecting a replica identity or a generated column.
Something like the attached, perhaps, may need more polish.
I'm not really sure about the business of adding a new pass value
-- it's clear that things don't work if we don't do *something* -- I'm
just not sure if this is the something that we want to do.
