I think this is a good idea to capture the failed replication stats.
But I'm wondering how you are deciding if
the replication failed or not? Not all cases of ReplicationSLotRelease
are due to a failure. It could also be due to a planned dropping
of subscription or disable of subscription. I have not tested this but
won't the failed stats be updated in this case as well? Is that
correct?
