You can avoid this problem by creating a slot first on publisher with
something like:
postgres=# select pg_create_logical_replication_slot('s1', 'pgoutput',
false, true);
pg_create_logical_replication_slot
------------------------------------
(s1,0/01BFF178)
(1 row)
Then while creating subscription you can use the above created slot as follows:
db1=# create subscription sub1 connection 'dbname=postgres'
publication pub1 WITH(create_slot=false, slot_name='s1');
CREATE SUBSCRIPTION

With Regards,

I am aware of this workaround solution. When I encountered the “create subscription” stuck problem, I did a Google search, then I found the old discussion thread that mentioned a workaround, so I did further search and eventually figured out the workaround.
I think it’s worth resolving this issue, because it avoids confusion from people who want to try or test logical replication logically, and allows the same script to run in both an pure local environment and a real non-local environment. WDYT?
Best regards,
