Review Comment:
Can we do something like this ?
```rust
let mut exprs = entries.into_iter().flat_map(|entry| {
let k = self.sql_expr_to_logical_expr(
*entry.key,
schema,
planner_context,
)?;
let v = self.sql_expr_to_logical_expr(
*entry.value,
schema,
planner_context,
)?;
vec![k,v]
}).collect<>();;
```
Haven't tried it out just a pseudo code
