Hello,
I'm working with an RDS instance running 12 that has an old subscription
that I can't seem to drop.
The logs show this, repeating every 5 seconds or so.
2021-07-09 16:08:07 UTC::@:[1637]:LOG: logical replication apply worker
for subscription "metro" has started
2021-07-09 16:08:07 UTC::@:[1637]:ERROR: could not connect to the
publisher: could not connect to server: Connection refused
Is the server running on host "dbp3" (108.200.30.101) and accepting
TCP/IP connections on port 5433?
dbp3 is long gone--the server no long exists.
It shows up here:

But not in here:

metro_prod │ mirror_admin │ t │ {metro_prod} │
off │ host=108.200.30.103 port=5433 user=postgres
dbname=metro_prod
(2 rows)
And it can't be disabled or dropped:
mirror_admin@metro_logical> alter subscription metro disable;
ERROR: subscription "metro" does not exist
Time: 24.263 ms
mirror_admin@metro_logical> drop subscription metro;
ERROR: subscription "metro" does not exist
Time: 23.648 ms
I did try deleting it directly from the pg_subscription table but that
failed with a permission denied error. My suspicion is that's because
of the RDS environment.
What else can I try to remove this old non-functional subscription?
Thanks,
Jeff Ross
