Timo Walther updated FLINK-17698:
---------------------------------
    Description: 
Ensure that all comparable types can be compared.

e.g. revisit 
`org.apache.flink.table.planner.codegen.GenerateUtils#generateCompare` and 
`org.apache.flink.table.runtime.typeutils.TypeCheckUtils#isComparable`

The RAW type is still compared by assuming the legacy raw type.
