I am not able to reproduce this failure. I suspect you made a mistake
in testing, because my test case before sending the patch was
basically the same as yours, except that I was testing with v13. But I
tried again with v12 and it seems fine:

[rhaas pgsql]$ createdb -p 5412
[rhaas pgsql]$ psql -c 'select version()' -p 5412
                                                    version
----------------------------------------------------------------------------------------------------------------
 PostgreSQL 12.3 on x86_64-apple-darwin19.4.0, compiled by clang
version 5.0.2 (tags/RELEASE_502/final), 64-bit
(1 row)
[rhaas pgsql]$ psql
psql (15devel)
Type "help" for help.

rhaas=# create subscription sub123s CONNECTION 'port=5412' PUBLICATION
pp with (slot_name =
from_v14);
NOTICE:  created replication slot "from_v14" on publisher
CREATE SUBSCRIPTION

Here's v9, fixing the issue reported by Fujii Masao.
