------------------------------------------
[~afedulov] When does it fail? Running all checks locally seems to pass. Also
CI does not complain.
> Can not select time attribute from a view

> Unfortunately the solution in [FLINK-36883] is not fully functional, because
> of a check in {{SqlToRelConverter}}. If the time attribute should be returned
> from a query using such a view it will fail with:
> {code}
> Conversion to relational algebra failed to preserve datatypes:
> validated type:
