it is possible to get two checkpoints for the same block. We take a checkpoint at a set interval, but also we take them when a withdrawal happens. If a withdraw happens to happen on the same block we would naturally take a checkpoint we’ll get two checkpoint events for the same block
It might be that core can not do this, but while it does, don't force checkpoints to be unique on block height.
Closes vegaprotocol/data-node#682 and vegaprotocol/vega#5700
