What this paper does with SQLancer

The single citation supplies terminology: the paper describes faults where a row is wrongly omitted from a result, or where a DELETE, INSERT or UPDATE wrongly changes the database state, and notes these are referred to by some as logic bugs. Diverse replication masks exactly this class of fault, which is why the term is introduced, but nothing of SQLancer's is used or measured. This paper measures what diverse database replication costs. Running several different DBMS implementations as replicas under snapshot isolation means a fault in one is masked by the others, improving dependability; the question is how much throughput and latency that redundancy consumes.
