Description
Aliases do not work after CASE expression:
$ ./bin/lint-query --query 'select 1 name'
#1: Unrecognized keyword. (near "name" at position 9)
$ ./bin/lint-query --query 'select case when 1 > 0 then "x" else "y" end AS name'
#1: Unrecognized keyword. (near "AS" at position 46)
#2: Unrecognized keyword. (near "name" at position 49)
