Make sure MyRocks tables do not have stats.records=0 as that confuses the optimizer.
They generally don't have stats.records=0, the the statistics are computed
based on GetApproximateSizes and GetApproximateMemTableStats. Still, when
there's nothing on disk and only a few records are in the MemTable, it
is possible that both calls will return 0, and the optimizer will see
stats.records=0, which may cause "impossible range" condition (even if
records_in_range() returned a non-zero value)
