Before this patch the following query:
SELECT assumeNotNull(argMax(dummy, 1))
FROM remote('127.1', system.one)
SETTINGS distributed_group_by_no_merge = 2
Leads to:
Code: 10. DB::Exception: Received from localhost:9000. DB::Exception: Not found column argMax(dummy, 1) in block: while executing 'INPUT : 0 -> argMax(dummy, 1) UInt8 : 0'.
Since it tries to execute function one more time, but shards will not
send this column when the query processed with
distributed_group_by_no_merge=2 (i.e. up to
WithMergeableStateAfterAggregation).
v0: no exception
v2: execut window functions
v3: throw exception, since executing window function in this case will
lead to messy output
