[BUG] View column aliasing does not work

Comienza ejecutando las tres definiciones de vistas SQL del issue y compara la consulta funcional cross_cloud_disks1 con las columnas con alias de cross_cloud_disks2 y cross_cloud_disks3. Rastrea el manejo de vistas y SELECT utilizado por el motor de consultas Go. Se considera terminado cuando las columnas con alias de las vistas se resuelvan correctamente y las tres consultas de ejemplo devuelvan los resultados esperados.

Describe the bug

Aliased view columns are not yet supported, as per screen capture.

To Reproduce

This works:

create view cross_cloud_disks1 as
select 'google' as vendor, name, split_part(split_part(type, '/', 11), '-', 2) as type, sizeGb from google.compute.disks where project = 'stackql-demo' and zone = 'australia-southeast1-a'
union
select 'aws' as vendor, volumeId as name, volumeType as type, size as SizeGb from aws.ec2.volumes where region = 'ap-southeast-2' 
;

select * from cross_cloud_disks1;

This does not work:

create view cross_cloud_disks2 as
select 'google' as vendor, name, split_part(split_part(type, '/', 11), '-', 2) as type, sizeGb as size from google.compute.disks where project = 'stackql-demo' and zone = 'australia-southeast1-a'
union
select 'aws' as vendor, volumeId as name, volumeType as type, size from aws.ec2.volumes where region = 'ap-southeast-2' 
;

select * from cross_cloud_disks2;

This simpler view also does not work:

create view cross_cloud_disks3 as
select 'google' as vendor, name, split_part(split_part(type, '/', 11), '-', 2) as type, sizeGb as size from google.compute.disks where project = 'stackql-demo' and zone = 'australia-southeast1-a'
;

select * from cross_cloud_disks3;
