I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

>
> Currently, the {{RexNodeToExpressionConverter}} in both planners are not
> fully support. There're many RexNodes can not be converted to Expressions.
> 1) RexFieldAccess -> GET call
> 2) Literals in interval types and complex types and TimeUnitRange
> 3) TRIM(BOTH/LEADING/HEADING, ..)
> ...
> We should have a comprehensive tests to cover all cases. A good idea is to
> verify with {{ExpressionConverter}} together.
