How to rename in-use logical replication publication?

Hello!

Postgres v11.12. Getting "ERROR:  publication "new_rep_pub" does not
exist" after renaming an existing publication. And the only way to get
it working seems to start from scratch. What am I missing?

On PUB side:
CREATE TABLE rep_test (int_col int PRIMARY KEY, ts_col timestamp);
INSERT INTO rep_test (int_col, ts_col) SELECT generate_series(1,10),
current_timestamp;
CREATE PUBLICATION rep_pub FOR TABLE rep_test;

On SUB side:
CREATE TABLE rep_test (int_col int PRIMARY KEY, ts_col timestamp)
CREATE SUBSCRIPTION rep_sub CONNECTION 'host=localhost port=54311
dbname=postgres' PUBLICATION rep_pub;

ALTER SUBSCRIPTION rep_sub DISABLE ;
ALTER SUBSCRIPTION rep_sub SET PUBLICATION new_rep_pub WITH ( refresh = false );

On PUB side:
ALTER PUBLICATION rep_pub RENAME TO new_rep_pub;

On SUB side:
ALTER SUBSCRIPTION rep_sub ENABLE ;

The PUB complains:

pg_catalog.set_config('search_path', '', false);

The SUB complains:

Yet it all looks like it should be OK:

postgres@postgres=# \dRp
