[Logical Replication] TRAP: FailedAssertion("rel->rd_rel->relreplident == REPLICA_IDENTITY_DEFAULT || rel->rd_rel->relreplident == REPLICA_IDENTITY_FULL || rel->rd_rel->relreplident == REPLICA_IDENTITY_INDEX"

Hi,
I am getting a server crash on publication server on HEAD for the below
test case.

Commit: b9c130a1fdf16cd99afb390c186d19acaea7d132

Data setup:
Publication server:
wal_level = logical
max_wal_senders = 10
max_replication_slots = 15
wal_log_hints = on
hot_standby_feedback = on
wal_receiver_status_interval = 1
listen_addresses='*'
log_min_messages=debug1
wal_sender_timeout = 0
logical_decoding_work_mem=64kB

Subscription server:
wal_level = logical
wal_log_hints = on
hot_standby_feedback = on
wal_receiver_status_interval = 1
log_min_messages=debug1
port=5433
logical_decoding_work_mem=64kB

Test case:
Publication server:
create table test(a int);
create publication test_pub for all tables;
alter table test replica identity NOTHING ;

Subscription server:
create table test(a int);
create subscription test_sub CONNECTION 'host=172.16.208.32 port=5432
dbname=postgres user=centos' PUBLICATION test_pub WITH ( slot_name =
test_slot_sub);

Publication server:
insert into test values(generate_series(1,5),'aa');

After executing the DML in publication server ,it crashed with the
mentioned assert.
