Dian Fu commented on FLINK-19116:
---------------------------------
After discussing with [~zhongwei] offline, I think this problem doesn't exist
and we could work around it. For example, If users want to create a literal of
Date type, users could use `lit("2013-01-01").to_date`. I'm closing this ticket
for now.
