[BUG] View column aliasing does not work

Start by running the three SQL view definitions in the issue and compare the working cross_cloud_disks1 query with the aliased columns in cross_cloud_disks2 and cross_cloud_disks3. Trace the view and SELECT handling used by the Go query engine. Done means aliased view columns resolve correctly and all three example queries return the expected results.

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;
