SYSTEM STOP MERGES not applying to newly created tables #91183

Company or project name

No response

Describe the unexpected behaviour

If I run SYSTEM STOP MERGES then issue CREATE TABLE then the merge will still run for the newly created table

Not sure if by design or a bug but I think its more intuitive if stop merges prevents merges running for all objects including newly created

Which ClickHouse versions are affected?

25.10.2.65

How to reproduce

Clickhouse client

-- If I stop merges THEN create a table then merges still run for the table

SYSTEM STOP MERGES;
drop table foo;
create table foo( x UInt32 ) ENGINE=ReplacingMergeTree() ORDER BY x;
insert into foo values ( 123 );
insert into foo values ( 123 );
insert into foo values ( 123 );
-- Will merge

-- If I create a table THEN stop merges then merges do not run

drop table foo;
create table foo( x UInt32 ) ENGINE=ReplacingMergeTree() ORDER BY x;
SYSTEM STOP MERGES;
insert into foo values ( 123 );
insert into foo values ( 123 );
insert into foo values ( 123 );
-- Will not merge

Expected behavior

Merges stopped for all tables including newly created
