I think the patch doesn't solve the problem completely. For example,
postgres=# create subscription sub3 connection 'dbname=postgres
port=5432 user=edb password=edb' publication abc with
(slot_name='none',create_slot=true);
ERROR: slot_name = NONE and create slot are mutually exclusive options
postgres=# create subscription sub3 connection 'dbname=postgres
port=5432 user=edb password=edb' publication abc with
(create_slot=true,slot_name='none');
ERROR: could not connect to the publisher: could not connect to
server: Connection refused
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Changing the order of subscription parameter changes the output. I
think the modifications should be done at the end of the function.
Attached a patch for the same.
