ALTER TABLE ... ON CLUSTER ... FETCH PARTITION not implemented?

[cyberhuman]

Describe the unexpected behaviour

ALTER TABLE FETCH PARTITION doesn't work for me when adding ON CLUSTER:

ALTER TABLE db.table ON CLUSTER cluster1
    FETCH PARTITION (col1, col2) FROM '{zk}:/clickhouse/tables/db/table/0-{shard}'

Query id: b0b224f9-893f-428d-8b9c-14c31a870654


0 rows in set. Elapsed: 0.013 sec. 

Received exception from server (version 22.11.4):
Code: 48. DB::Exception: Received from 10.100.0.241:9001. DB::Exception: Unsupported type of ALTER query. (NOT_IMPLEMENTED)

How to reproduce

• Which ClickHouse server version to use
  22.11.4

• Which interface to use, if matters
  I used clickhouse-client.

• Non-default settings, if any

• CREATE TABLE statements for all tables involved

• Sample data for all these tables, use clickhouse-obfuscator if necessary

• Queries to run that lead to unexpected result

Expected behavior
partitions must be fetched on all nodes in the cluster
