Francesco Guardiani commented on FLINK-26782:
---------------------------------------------
I wasn't able to complete this as it needs as prerequisite a solution for the
legacy UDFs, because those still rely on PlannerExpression. Either we remove
the legacy UDFs, or we need to adapt them to the new type inference stack.
This is the commit to perform the removal
