   Hi @terrymanu @iamhucong,
   
   Went through the full task list on this issue and everything appears 
resolved now:
   
   ALTER SYSTEM ADD/DROP FOLLOWER/OBSERVER — merged via #37552
   RECOVER DATABASE/TABLE/PARTITION (all variants, with and without <id>/AS 
<new_name>) — merged via #39512
   array_cum_sum(Array<T>) — no code changes needed. Verified by parsing all 
four example cases from the [official 
docs](https://doris.apache.org/docs/2.1/sql-manual/sql-functions/scalar-functions/array-functions/array-cum-sum/)
 against current master using the ANTLR grammar directly:
   SELECT array_cum_sum(int_array) FROM array_cum_sum_test;
   SELECT array_cum_sum(double_array) FROM array_cum_sum_test;
   SELECT array_cum_sum(['a', 1, 'b', 2, 'c', 3]);
   The accompanying CREATE TABLE array_cum_sum_test (...) setup statement
   All four parse cleanly — array_cum_sum falls through the existing generic 
completeRegularFunction → regularFunctionName → identifier path, and array 
literals are already handled by the existing arrayExpression rule. No grammar, 
visitor, or test changes required (per this issue's own note: "If a SQL case 
can be executed successfully without any code changes, there is no need to add 
a corresponding test assert file").
   
   I don't see any remaining scope from the original task list. Would it be OK 
to close this one out?
