I just found that the FeedPolicyDropStatement is not used in the AQL parser (AQL.jj) nor anywhere else: https://github.com/apache/incubator-asterixdb/blob/master/asterix-aql/src/main/java/org/apache/asterix/aql/expression/FeedPolicyDropStatement.java
Do we still need that statement? If not, I will remove it. Best, Yingyi
