Here is the sql that fetch is deterministic and offset is dynamic
`select * from emp order by ename limit 1 offset ?`
**RelMdRowCount#getRowCount** will return 14d, because it always return
rowCount when offset is dynamic.
```
if (rel.offset instanceof RexDynamicParam) {
return rowCount;
}
```
Obviously, rowCount will not exceed 1 because LIMIT 1. We can improve it
