Dear Abrahim

It is possible that a shared library is loaded even if shared_preload is not set
and CREATE EXTENSION is not executed. Per my understanding the specified plugin
name would be searched by the same rule as other libraries. See [1].
Another example is 'test_decoding'. It is a sample plugin which postgres-core
includes. Anyone can use the plugin via SQL function. CREATE EXTENSION is not needed.
```
postgres=# SELECT pg_create_logical_replication_slot('slot', 'test_decoding');
pg_create_logical_replication_slot
------------------------------------
(slot,0/1829CE0)
(1 row)
```
> I will create a new container without Citus extension package ...
Yeah, it is quite helpful to understand the issue correctly. Thanks for working on it.
