Hello list,

I am trying to make use of the synchronized logical replication slots on PG18.  I have all the requirements met, and if I create a logical replication slot manually with failover=true it is replicated to the second node.  Unfortunately I have two connections that create their own logical replication slots with failover false.  AWS DMS is one for example, but both have the same problem.  Is there any way to change the failover parameter on an existing logical replication slot from false to true?  Or set it so that all logical replications slots are synchronized so that they don't have to be individually created or altered for replication=true?  Or force them all to true?  Any other ideas?

Thanks!
