Hi,
A newbie question: how do I delete lingering replication slots? When
creating Subscription for logical replication, the CREATE SUBSCRIPTION
stuck and didn't return. After ctrl-c and aborted the command, the
master database have lingering replication slots that I can't delete
because the active is true. Do I just kill the pid?
Thanks!
SELECT * FROM pg_replication_slots ;
slot_name |plugin| slot_type |datoid|database| temporary | active |
active_pid | xmin | catalog_xmin | restart_lsn| confirmed_flush_lsn
