    Instead of querying the existing mappings for overlap and either
    updating or inserting depending on the result, we now delete
    overlapping mappings first and then only insert.
    This is roughly twice as fast. But of course still a horrible
    setup compared to some kind of UPSERT functionality which is
    unfortunately missing in current PostgreSQL.
