Re: [HACKERS] Server Crashes if try to provide slot_name='none' atthe time of creating subscription. - Mailing list pgsql-hackers

While testing with logical replication, I've found that the server
hangs if we create a subscription to the same server. For example,

$ ./pg_ctl -D Test start -o "-p 5432"
$ ./psql -p 5432 postgres -c "CREATE PUBLICATION abc for all tables
with (publish='delete');"
$ ./psql -p 5432 postgres -c "create subscription sub connection
'dbname=postgres port=5432 user=edb password=edb' publication abc with
(slot_name='abcslot');"
NOTICE:  synchronized table states
LOG:  logical decoding found initial starting point at 0/162DF18
DETAIL:  Waiting for transactions (approximately 1) older than 560 to end.

And, it hangs. Is this an expected behavior?
