Review Comment:
Now we pass the compilation. But it still fails `array.slt`:
```
External error: query failed: DataFusion error: Error during planning: Error
during planning: Coercion from [Int64, Int64] to the signature
ArraySignature(ArrayAndIndex) failed. and No function matches the given name
and argument types 'array_element(Int64, Int64)'. You might need to add
explicit type casts.
Candidate functions:
array_element(array, index)
[SQL] select make_array(1, 2, 3)[1:2], make_array(1.0, 2.0, 3.0)[2:3],
make_array('h', 'e', 'l', 'l', 'o')[2:4];
at test_files/array.slt:859
Error: Execution("1 failures")
error: test failed, to rerun pass `-p datafusion-sqllogictest --test
sqllogictests`
```
