Description
As of versions 10.2 and 10.3.0, the class Value_source::Context (used for equal expression propagation) uses Item m_compare_type to store comparison type of the operation. This is not friendly to pluggable data types. To make pluggable data types use equal expression propagation, we'll remove m_compare_type and add const Type_handler *m_compara_handler instead.
